  • using php Download File From a given URL by passing username and password for http authentication

    - by Acharya
    Hi all, I need to download a text file using php code. The file is having http authentication. What procedure I should use for this. Should I use fsocketopen or curl or Is there any other way to do this? I am using fsocketopen but it does not seem to work. $fp=fsockopen("www.example.com",80,$errno,$errorstr); $out = "GET abcdata/feed.txt HTTP/1.1\r\n"; $out .= "User: xyz \r\n"; $out .= "Password: xyz \r\n\r\n"; fwrite($fp, $out); while(!feof($fp)) { echo fgets($fp,1024); } fclose($fp); Here fgets is returning false. Any help!!!

  • PHP inheriting/extending a particular instance of an Object

    - by delta9
    Is there any way to force PHP to extend an existing/particular (and for that matter, already instantiated) instance of an object? This imaginary code should explain what I am wondering: class Base { public $var; function __construct($var){ $this->var = $name; } } class Extender extends Base { function __construct($parent) { parent = $parent; } } $base = new Base('yay!'); $extender = new Extender($base); echo 'Extended base var value: '.$extender->var.'<br/>'; Output (would be): Extended base var value: yay! To be clear, I am wanting to instantiate an object that extends a PARTICULAR INSTANCE of another object, one that has already been instantiated. I am aware that I can pass a reference to an object to another object (via it's constructor function) and then add it as a property of the receiving object, I'm wondering if there is a real way to do this?

  • PHP getting full server name including port number and protocol

    - by vivid-colours
    In PHP, is there a reliable and good way of getting these things: Protocol: i.e. http or https Servername: e.g. localhost Portnumber: e.g. 8080 I can get the server name using $_SERVER['SERVER_NAME']. I can kind of get the protocol but I don't think it's perfect: if(strtolower(substr($_SERVER["SERVER_PROTOCOL"],0,5))=='https') { return "https"; } else { return "http"; } I don't know how to get the port number though. The port numbers I am using are not 80.. they are 8080 and 8888. Thank you.

  • PHP MYSQL query result "RANKING"

    - by fkessler
    Hi, I need to get a list of users Ranking by points and from my command line (MySQL) is was able to generate the necessary code: SET @rank=0; SELECT rank, iduser, pontos FROM ( SELECT @rank:=@rank+1 AS rank, SUM(points.points) AS pontos, points.iduser, users.name, users.idade FROM points INNER JOIN users ON (points.iduser = users.id) WHERE (users.idade >= %s) AND (users.idade <= %s) GROUP BY points.iduser ORDER BY pontos DESC) AS totals WHERE iduser = %s The problem is that I need this to run on AMFPHP and I´ve tested it in a test PHP file and seems that I can´t use the SET and SELECT in the same "mysql_query". I´ve looked and some used to mysql_query to do this (I´ve tested it and it works), but can I trust this to be effective and error free? Does it work like in MySQL transactions or setting the @rank in a seperated query may cause unexpected results?

  • [JS] How to manipulate a PHP Array in javascript?

    - by rasouza
    I have an Array in PHP which contains data from database. And it prints out also as a table in the same page which has an AJAX delete function. Trying to explain better The array contains debt sums related to many people, it is the application's main function. In the same page, there is a table containing every debt record related to the array, which can be deleted or edited using AJAX. I have coded the part of deleting the record and removing the TR entry, but it's not enough: I'd like to change also the debt sum using AJAX which is an PHP Array. What I have I have the JS function which removes the TR when the delete button is clicked // TR Fading when deleted $('.delete') .click(function() { $.ajax({ type: 'GET', url: 'history/delete/id/'+$(this).attr('id') }); $(this).parent().parent().fadeOut(); return false; }); and I have the PHP array (image)

  • Help with PHP MySQL join

    - by kester martinez
    Please help me to understand proper join syntax. I have table named inventory which has: trans_id trans_items items -> item_id trans_user employees -> person_id trans_date trans_comment trans_inventory As you can see above, trans_items is a foreign key in items table, and trans_user is a foreign key in employees table. Now what I want to do is to display in HTML the inventory table, but instead of displaying the item id, I want the ITEM NAME to be displayed. Here is what I have done. Please note I'm using CodeIgniter. public function getData(array $inputs) { $this->db->select('trans_items, trans_user, trans_date, trans_inventory, trans_comment'); $this->db->from('inventory'); $this->db->order_by('trans_date desc'); return $this->db->get()->result_array(); }

  • PHP attempting to make JavaScript friendly timestamp, failing, returns 1.34899651119E+12

    - by chris
    Well, not sure whats going on. I have been trying to follow by examples I have found here on stack, on google, even an answer someone gave me a week+ ago, which unfortunately I wasn't able to test until today. Anyway I am attempting to generate a javascript friendly timestamp via php so I can get my times synced up. The best logic I could find overall was something dealing with microtime. However that doesn't seem to work as expected, not even in the slightest. Right now I am using microtime(true)*1000; and am getting 1.34899651119E+12 for the result. Did I some how manage to mess up that one tiny line of code, Im not sure.

  • why my array is losing it's contents when I refresh the page?

    - by Fernando SBS
    I have created an: var checkboxFarm = new Array(); then I want to record a checkbox status in that array, as there are 11 checkboxes. Button.addEventListener("click", function() { rp_farmAtivada(index); }, false); when clicked change the variable in the array: function rp_farmAtivada(index) { checkboxFarm[index] = !checkboxFarm[index]; }; but every time I refresh the page it loses all the checkboxes status and I'm aware that all that array gets the "undefined" value. the checkboxFarm array is defined in the beginning of the script, so it should have a global scope. Am I missing something?

  • PHP regular expression subpattern behaviour

    - by codecowboy
    I want to match both the src and title attributes of an image tag: pattern: <img [^>]*src=["|\']([^"|\']+["|\'])|title=["|\']([^"|\']+) target: <img src="http://someurl.jpg" class="quiz_caption" title="Caption goes here!"> This pattern gives me one unwanted match, title="content", and the match I actually want which is the value between the quotes after the word 'title', i.e 'content'. So, my matches are: <img src="http://someurl.jpg http://someurl.jpg title="Caption goes here!" Caption goes here! Is there a way to avoid the third of these matches? I'm using PCRE in PHP 5.2.x

  • Badword filter in PHP?

    - by morpheous
    I am writing a badword filter in PHP. I have a list of badwords in an array and the method cleanse_text() is written like this: public static function cleanse_text($originalstring){ if (!self::$is_sorted) self::doSort(); return str_ireplace(self::$badwords, '****', $originalstring); } This works trivially, for exact matches, but I wanted to also censor words that have been disguised like 'ab*d' where 'abcd' is a bad word. This is proving to be a bit more difficult. Here are my questions: Is a badword filter worth bothering with (it is a site for professionals so a certain minimum decorum is required - I would have thought) Is it worth the hustle of trying to capture obvious work arounds like 'f*ck' - or should I not attempt to filter those out. Is there a better way of writing the cleanse_text() method above?

  • PHP> Sort query results by name while letting each letter be on the top sometimes

    - by Don
    Hi, I'm currently working on a site that will display a list of online shops, Each shop will be stored on my database and I'll be using PHP to select and display them. But since those shops will pay me, I want to let each shop to be on the top of the list sometimes, (for example if the shop name starts with a "Z", they will probably complain for being on the bottom of the list all the time, so I want to keep it fair). So I thought about letting each letter be on the top of the list for an hour, but i have no idea how to do that.. Is that even possible? Thanks in advance!

  • PHP: read all files but randomly?

    - by mathiregister
    hi there, i wonder if there's a way of reading a directory in a random order. With the following code i'm running through the directory thumbs and it's printing images on my website. However, they are always read alphabetically and i wonder if there's a way in doing this randomly? <?php $path = 'thumbs'; if ($handle = opendir($path)) { while (false !== ($file = readdir($handle))) { if ($file != '.' && $file != '..' && $file != '.DS_Store' && $file != 'Thumbs.db') { print "<img class='thumb' src='$path/$file'/>"; } else { //no proper file } } closedir($handle); } ?> thank you for your suggestions! regards

  • conditional while loop in php?

    - by julio
    I'm pretty sure there's an obvious answer for this-- hoping someone can help me-- I need to do a PHP while loop, but only if a variable is true. And I can't really put the while loop in an "if" statement, which seems like the obvious thing to do, since the code block is huge and it would be ugly and confusing. Do I need to break out the code in the loop into a function, or is there an easier way to deal with this? Here's the basic idea: if(condition){ while(another_condition){ //huge block of code loops many times } } else { // huge block of code runs once } I want the huge block of code to execute regardless of the state of the condition variable-- but only to execute once if condition is false, and execute for as long as another_condition is true if condition is true. Hope that's clear! The following code doesn't work, but gives an idea of what I want to accomplish: if(condition){ while(another_condition){ } // huge block of code if (condition){ } } // closes the while loop-- obviously throws an error though! thanks in advance.

  • Suppress error with @ operator in PHP

    - by Mez
    In your opinion, is it ever valid to use the @ operator to suppress an error/warning in PHP whereas you may be handling the error? If so, in what circumstances would you use this? Code examples are welcome. Edit: Note to repliers. I'm not looking to turn error reporting off, but, for example, common practice is to use @fopen($file); and then check afterwards... but you can get rid of the @ by doing if (file_exists($file)) { fopen($file); } else { die('File not found'); } or similar. I guess the question is - is there anywhere that @ HAS to be used to supress an error, that CANNOT be handled in any other manner?

  • php class basic question

    hi <?php class myClass { var $input; var $output; function myClass($input) { $output = 'You entered: ' . $input; return $output; } } $test = new myClass; echo $test->myClass(123); ?> this works, but returns this warning: Warning: Missing argument 1 for myClass::myClass() I read in to this, and seems that the constructor is expecting a value, so by adding: function myClass($input='') the warning is removed, but this seems so unnecessary? could someone enlighten me as to why it's required to define a value to prevent that warning? thanks for any pointers

  • PHP speed optimisation.

    - by Petah
    Hi, Im wondering about speed optimization in PHP. I have a series of files that are requested every page load. On average there are 20 files. Each file must be read an parsed if they have changed. And this is excluding that standard files required for a web page (HTML, CSS, images, etc). EG - client requests page - server outputs html, css, images - server outputs dynamic content (20+/- files combined and minified). What would be the best way to serve these files as fast as possible?

  • How to work around a site forbidding me to scrape their images with PHP

    - by Petruza
    I'm scraping a site, searching for JPGs to download. Scraping the site's HTML pages works fine. But when I try getting the JPGs with CURL, copy(), fopen(), etc., I get a 403 forbiden status. I know that's because the site owners don't want their images scraped, so I understand a good answer would be just don't do it, because they don't want you to. Ok, but let's say it's ok and I try to work around this, how could this be achieved? If I get the same URL with a browser, I can open the image perfectly, it's not that my IP is banned or anything, and I'm testing the scraper one file at a time, so it's not blocking me because I make too many requests too often. From my understanding, it could be that either the site is checking for some cookies that confirm that I'm using a browser and browsing their site before I download a JPG. Or that maybe PHP is using some user agent for the requests that the server can detect and filter out. Anyway, have any idea?
