• Counting comma seperated values in php,how to?

  - by Jay

  Hey folks, I have a variable holding values separated by a comma (Implode), I'm trying to get the total count of the values in that variable however, count() is just returning 1. I've tried converting the comma separated values to a properly formatted array which still spits out1. So heres the quick snippet where the sarray session equals to value1,value2,value3: $schools = $_SESSION['sarray']; $result = count($schools); Any help would be appreciated.

• php/mysql append state to city

  - by mike

  Hello, Having a hard time figuring out the best way to do this... I have a search function that takes "search terms" and "search location". In the location input, I have an suggestion feature that brings up "city, state abbreviation" but it seems some users just do not use it(or can't) so they end up entering just a city name... I need to append the state abbreviation after the form is submitted. I have a table with all city and state names in the U.S. but the problem is... there are multiple cities with the same name in different states... I would like to add the state abbreviation for the state that the city is most popular for(does that make sense?). For example, if the user enters "Miami" I would like it to become "Miami, FL" as opposed to "Miami, WV"... Any ideas? Thanks!

• break up recursive function in php

  - by Mike

  What is the best way to break up a recursive function that is using a ton of resources For example: function do_a_lot(){ //a lot of code and processing is done here //it takes a lot of execution time if($true){ //if true we have to do all of that processing again do_a_lot(); } } Is there anyway to make the server only have to take the brunt of the first execution and then break up the recursion into separate processes? Or am I dreaming?

• PHP Doctrine: filtering data which is already loaded?

  - by ropstah

  I'm new to Doctrine and ActiveRecord. How should I filter a table after it has been loaded? (i suppose this is preferred over sending multiple queries?) Is this 'good' or 'bad'? class UserTable extends Doctrine_Table { function filterByGroup($group) { $ut = new UserTable(); foreach($this as $u) { if($u->group = $group) $ut->add($u); } return $ut; } }

• PHP: exif_imagetype() not working?

  - by Karem

  I have this extension checker: $upload_name = "file"; $max_file_size_in_bytes = 8388608; $extension_whitelist = array("jpg", "gif", "png", "jpeg"); /* checking extensions */ $path_info = pathinfo($_FILES[$upload_name]['name']); $file_extension = $path_info["extension"]; $is_valid_extension = false; foreach ($extension_whitelist as $extension) { if (strcasecmp($file_extension, $extension) == 0) { $is_valid_extension = true; break; } } if (!$is_valid_extension) { echo "{"; echo "error: 'ext not allowed!'\n"; echo "}"; exit(0); } And then i added this: if (exif_imagetype($_FILES[$upload_name]['name']) != IMAGETYPE_GIF OR exif_imagetype($_FILES[$upload_name]['name']) != IMAGETYPE_JPEG OR exif_imagetype($_FILES[$upload_name]['name']) != IMAGETYPE_PNG) { echo "{"; echo "error: 'This is no photo..'\n"; echo "}"; exit(0); } As soon when I added this to my imageupload function, the function stops working. I dont get any errors, not even the one i made myself "this is no photo", what could be wrong? Just checked with my host. They support the function exif_imagetype()

• Unique identification string in php

  - by NardCake

  Currently me and my friend are developing a website, for what we will call 'projects' we just have a basic auto increment id in the database used to navigate to projects such as oururl.com/viewproject?id=1 but we started thinking, if we have alot of posted projects thats going to be a LONG url. So we need to somehow randomly generate a alphanumerical string about 6 characters long. We want the chance of the string being duplicated being extremely low and of course we will query the database before assigning an identifier. Thanks for anyhelp, means alot!

• find and replace values in csv using PHP

  - by peirix

  I'd think there was a question on this already, but I can't find one. Maybe the solution is too easy... Anyway, I have a csv and want to let the user change the values based on a name. I've already sorted out creating new name+value-pairs using the fopen('a') mode, using jQuery to send the AJAX call with newValue and newName. But say the content looks like this: host|http:www.stackoverflow.com folder|/questions/ folder2|/users/ And now I want to change the folder value. So I'll send in folder as oldName and /tags/ as newValue. What's the best way to overwrite the value? The order in the list doesn't matter, and the name will always be on the left, followed by a |(pipe), the value and then a new-line. My first thought was to read the list, store it in an array, search all the [0]'s for oldName, then change the [1] that belongs to it, and then write it back to a file. But I feel there is a better way around this? Any ideas? Maybe regex?

• php $_SESSION[document_root] too far down the tree

  - by Idealflip

  Hi, I have multiple sub-domains within the document_root. And multiple folders/classes within those sub-domain folders. I need something that will help me with my include_once paths, but $_SESSION[DOCUMENT_ROOT] goes too far down. And if I were to use this, and transfer the website folder later, all my include_once paths will/might break. Hope my question is clear... Any recommendations?

• Make any posible combination of one string with php

  - by Johan

  I need an algorithm that return all possible combination of all characters in one string. I've tried: $langd = strlen($input); for($i = 0;$i < $langd; $i++){ $tempStrang = NULL; $tempStrang .= substr($input, $i, 1); for($j = $i+1, $k=0; $k < $langd; $k++, $j++){ if($j > $langd) $j = 0; $tempStrang .= substr($input, $j, 1); } $myarray[] = $tempStrang; } But that only returns the same amount combination as the length of the string. Say the $input is = "hey", the result would be: hey, hye, eyh, ehy, yhe, yeh.

• php - using file() incrementally?

  - by NeedBeerStat

  I'm not sure if this is possible, I've been googling for a solution... But, essentially, I have a very large file, the lines of which I want to store in an array. Thus, I'm using file(), but is there a way to do that in batches? So that every,say, 100 lines it creates, it "pauses"? I think there's likely to be something I can do with a foreach loop or something, but I'm not sure that I'm thinking about it the right way... Like $i=0; $j=0; $throttle=100; foreach($files as $k => $v) { if($i < $j+$throttle && $i > $j) { $lines[] = file($v); //Do some other stuff, like importing into a db } $i++; $j++; } But, I think that won't really work because $i & $j will always be equal... Anyway, feeling muddled... Can someone help me think a lil' clearer?

• PHP File Upload + jQuery

  - by st4ck0v3rfl0w

  Hello Everyone, So I have my upload script working just fine, but now it's a matter of making it look the way I want for my layout. <input type="file" name="userfile" id="userfile"/> This obviously shows a textbox with a Choose File button. What I really need is my own custom button (which will ultimately be an image) that upon successful file select (not upload quite yet) triggers a jQuery event to show a div. I do NOT want the filename textbox to show. Basic steps outlined below. User clicks on image button to upload their file User selects file jQuery shows a div with more fields User clicks submit and file is uploaded

• How can I use "PHP Simple HTML DOM Parser" to get the contents of an <h1></h1> tag?

  - by KeriLynn

  I'm new to PHP =) Right now I am using PHP includes for my site template. I have my header, containing all my <head></head> info. What I want to do is write a code that will take the contents of the <h1></h1> tag from the page, and echo it into the <title></title> tag in my header.php include. I got the PHP Simple HTML DOM Parser from here: http://simplehtmldom.sourceforge.net/, and I found a code (I forget where in all my googling) that goes like this: <?php $url = (!empty($_SERVER['HTTPS'])) ? "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] : "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']; $html = file_get_html('http://www.google.com/'); foreach($html->find('#content h1') as $element){ echo $element->plaintext;} ?> That I think is supposed to echo the h1 tag contents? Like I said, I'm new to PHP and I only know the basics, and I don't know really know any OOP (yet), so I'm sorry if I'm asking a dumb question. It looks like it's getting the current page, then putting the contents of the h1 tag into the variable $element, and then echoing it. But nothing happens when I put it into my page. Can anyone help me with what I'm doing wrong? Thank you for reading!! =)

• PHP: parse $_FILES[] data in multidimesional array

  - by superUntitled

  I having been looking around for an answer to this and have not found an answer anywhere, I am hoping someone has done this before! I have a form that allows for dynamic duplication of the form fields. The form allows for file uploads and text input, so the data is sent in both $_POST and $_FILES arrays. The the initial set of inputs look like this: <input type="text" name="primary[1][text]" /> <input type="file" name="primary[1][file]" /> <input type="text" class="a" name="secondary[1][text][]" /> <input type="file" name="secondary[1][file][]" /> When duplicated the fields are incremented, they look like this: <input type="text" name="primary[2][text]" /> <input type="file" name="primary[2][file]" /> <input type="text" class="a" name="secondary[2][text][]" /> <input type="file" name="secondary[2][file][]" /> To complicate matters, the "secondary" form fields can also be duplicated (thus the [] at the end of the secondary name array. How can I parse the posted $_FILES array? I have tried something like this: foreach ($_FILES['question'] as $f_num) { echo $f['file']['name']; } but I get an "Undefined index: file... " error.

• Echo a multidimensional array in PHP

  - by Jennifer

  I have a multidimensional array and I'm trying to find out how to simply "echo" the elements of the array. The depth of the array is not known, so it could be deeply nested. In the case of the array below, the right order to echo would be: This is a parent comment This is a child comment This is the 2nd child comment This is another parent comment This is the array I was talking about: Array ( [0] => Array ( [comment_id] => 1 [comment_content] => This is a parent comment [child] => Array ( [0] => Array ( [comment_id] => 3 [comment_content] => This is a child comment [child] => Array ( [0] => Array ( [comment_id] => 4 [comment_content] => This is the 2nd child comment [child] => Array ( ) ) ) ) ) ) [1] => Array ( [comment_id] => 2 [comment_content] => This is another parent comment [child] => Array ( ) ) )
