  • PHP: Collect all variables passed to a function as array?

    - by Industrial
    Hi everybody, I was thinking about the possibility of accessing all the variables that are passed into an function, and merge them into an array. (Without passing variables into an array from the beginning) Pseudo-code: // Call function newFunction('one', 'two', 'three' ) ;// All values are interpreted as a one rray in some way // Function layout newFunction( ) { // $functionvariables = array( All passed variables) foreach ($functionvariable as $k => $v) { // Do stuff } }

  • How do I generate an Array string from an array in memory (php).

    - by Itay Moav
    I need to create a big array in my code, I have the values in several tables (for easy management). I select it and now I have all the values in an array, in memory in the way I want. My problem, I need to write this array down, into the code. Is there a way to take an array which sits in the memory and translate it into a string "array('g'='h','b'='d'....)" which I can then echo and just copy-paste into my code?

  • PHP, MySQL - would results-array shuffle be quicker than "select... order by rand()"?

    - by sombe
    I've been reading a lot about the disadvantages of using "order by rand" so I don't need update on that. I was thinking, since I only need a limited amount of rows retrieved from the db to be randomized, maybe I should do: $r = $db->query("select * from table limit 500"); for($i;$i<500;$i++) $arr[$i]=mysqli_fetch_assoc($r); shuffle($arr); (i know this only randomizes the 500 first rows, be it). would that be faster than $r = $db->("select * from table order by rand() limit 500"); let me just mention, say the db tables were packed with more than...10,000 rows. why don't you do it yourself?!? - well, i have, but i'm looking for your experienced opinion. thanks!

  • How do I turn a PDF email attachment to an image (jpg) in a PHP page?

    - by user351630
    Hi guys. Long time viewer, first time question asker. I'm trying to have my personal website parse through my mail box for attachments from a certain subscription list, and then be able to view the PDF attachments as images, preferably jpg. With the help of this: http://www.linuxscope.net/articles/mailAttachmentsPHP.html I'm currently using imap_base64() to decode the MIME data and create the PDF. However, I hate using PDF readers in general and I thought it would be a lot more streamlined if I could just view it as an image instead. I've heard for convert with ImageMagick, but would I need to actually write the PDF to a directory before using this, or can I convert somehow directly from the MIME data in the email? Thanks in advanced!

  • PHP reg expr. replace ALL URLs except img src URLs

    - by zilveer
    Hi, I have searched but havent been able to find my answer. It follows like: I would like to replace all URL in a string to links except the URLs within img src tag. I have a regular expression for replacing all the URLs to links, but would like it to NOT replace the URLs within img src="" attribute. How can i do this? Here is the code for replacing all URLs: /*** make sure there is an http:// on all URLs ***/ $str = preg_replace("/([^\w\/])(www\.[a-z0-9\-]+\.[a-z0-9\-]+)/i", "$1http://$2",$str); /*** make all URLs links ***/ $str = preg_replace("/([\w]+:\/\/[\w-?&;#~=\.\/\@]+[\w\/])/i","<a target=\"_blank\" href=\"$1\">$1</a>",$str); /Regards

  • Can I prevent IMAP from grabbing files over X mb using PHP?

    - by mike
    I'm building a little script that will connect to an IMAP account and grab the content of the email and also the attachments. It works well for the most part, but when a really large file comes in, it causes the script to time out. Is there any way that I can check the file size before trying to grab it? I think that would be the simplest solution. Otherwise, I may have to upgrade to a server that has more memory.

  • Are there any Open source Admin Panel based on PHP and jQuery?

    - by Pablo
    I've try many CMS flavors like MODx, Drupal, Joomla for the admin Panel but they can't seem to manage my existing data, like the users. Im planing on building a admin Control Panel for my site and i was wondering if there is something out there which i can start working with instead of starting from scratch. UPDATE: To do simple tasks like: Managing my users Managing my content( the site is an image sharing site, so in this case images) I was looking more into a graphical interface more then a system as i have lots of costume content and data like the users.

  • What's wrong with my If-statement to check uploaded file? (PHP)

    - by ggfan
    I am trying to test if the uploaded file is the image type I want. If it isn't a gif,jpeg, png, it should echo "Problem". But when I execute this code, it always says there's a problem. What's wrong with my if statement? $uploadfile_type=$_FILES['userfile']['type']; if ( ($uploadfile_type !='image/gif') || ($uploadfile_type !='image/jpeg') || ($uploadfile_type !='image/png')) { echo 'Problem: file is not a gif or jpeg or png!'; exit; } This code works when I am only checking one type of image. Ex: if($uploadfile_type !='image/gif') -- this statement would work but when I add a OR it doesn't.

  • In PHP how do a translate a date to numerical format not knowing the format of the string beforehand

    - by stormist
    Examples of the translations I need to do: $stringDate = "November 2009"; $output = "11/09"; $stringDate = "October 1 2010"; $output = "10/01/2010"; $stringDate = "January 2010"; $output = "01/10"; $stringDate = "January 9 2010"; $output = "01/09/2010"; Note that I do not know which format the $stringDate will be in and the lack of commas in the month day year set. Thanks for any help anyone might offer.

  • Does a native php (5+) function exist that does the following in 1 line?

    - by Vinh
    function array_value_from_key($array,$key) { return !empty($array[$key]) ? $array[$key] : null; } The reason I ask is because I have a class function that returns an array. Instead of having to do $myArray = myClass::giveMeArray(); $myValue = $myArray[$myKey]; I'd like to do something along the lines of $myValue = array_value_from_key(myClass::giveMeArray(),$myKey); When an object is returned, you can chain the object such as $myValue = myClass::giveMeObject()->aValue; Voila, nice and clean.. not being able to find what seems to be a simple and trivial function is driving me crazy... PS.. one more example of how I'd like to use such a function if(arrayKeyVal(aClass::giveMeArray(),$myKey)) { do_something(); }

  • PHP - Pull out array keys that have matching values?

    - by MAZUMA
    Is there a way to look inside an array and pull out the keys that have keys with matching values? Questions like this have been asked, but I'm not finding anything conclusive. So if my array looks like this Array ( [0] => Array ( [title] => Title 1 [type] => [message] => ) [1] => Array ( [title] => Title 2 [type] => [message] => ) [2] => Array ( [title] => Title 3 [type] => [message] => ) [3] => Array ( [title] => Title 2 [type] => Limited [message] => 39 ) [4] => Array ( [title] => Title 4 [type] => Offline [message] => 41 ) [5] => Array ( [title] => Title 5 [type] => [message] => ) And I want to get this Array ( [1] => Array ( [title] => Title 2 [type] => [message] => ) [3] => Array ( [title] => Title 2 [type] => Limited [message] => 39 ) )

  • (PHP) How do I get XMLReader behave like SimpleXML with Xpath? (Large directory like XML file)

    - by AESM
    So, I've got this huge XML file (10MB and up) that I want to parse and I figured instead of using SimpleXML, I'd better use XMLReader. Since the performance should be way better, right? But since XMLReader doesn't work with XPath... The xml is like this: <root name="bookmarks"> * <dir name="A directory"> <link name="blablabla"> <dir name="Sub directory"> ... </dir> * </dir> * <link name="another link"> </root> With SimpleXML combined with Xpath, I would simple do like: $xml = simplexml_load_file('/xmlFile.xml'); $xml-xpath('/root[@name]/dir[@name="A directory"]/dir[@name="Sub directory"]'); Which is so simple. But how do I do this with just using XMLReader? Ps. I'm converting the resulting node to DOM/SimpleXML to get its inner contents. Like this: $node = $xr-expand(); $dom = new DomDocument(); $n = $dom-importNode($node, true); $dom-appendChild($n); $selectedRoot = simplexml_import_dom($dom); Is this ok? ... Thanks!
