file_get_contents on a php file

[mort]

Hey all

 

What I am trying to do is write a script that does file_get_contents on a directory of javascript files, and appends each file to the end of a variable. This big string is then used to output to a file and have one big javascript file, redusing HTTP requests on the server.

 

The problem I have is that some of the javascript files I have are actually php files that use header() to read it as javascript, however when I do file_get_contents on a php file, it returns the actual php code instead of the rendered javascript.

 

Any ideas?

Is the PHP only used to send along the header? If so, don't use any PHP at all and let (or make) your web server provide the correct content type header for JavaScript.

would it be possible to make an exclusion list ?

not sure what you mean really

 

the php is used to send the header, but it also dynamically builds the javascript as well

 

basically if I have

 

code.php

<? echo "hello world";  ?>

and do

 

index.php

<? echo file_get_contents('code.php'); ?>

how do I get that to output

hello world

instead of

<? echo "hello world";  ?>

also all of my .php javascript files already have

 

header("content-type: application/x-javascript"); 

[dgoosens]

maybe you could post one of those files here...

 

also, what about an exclusion list ?

file_get_contents only retrieves the html of the page after is has been rendered.  Try:

 

/**
* Fetch the specified page source, even if fopen_url_wrapper is disabled
* For that purpose, we use the curl wrapper. It should work everywhere
* 
* @param String $url The url to fetch
* @return String The page source code
*/
function getPage($url="http://www.example.com/"){
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_FRESH_CONNECT,TRUE);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,5);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,TRUE);
curl_setopt($ch,CURLOPT_REFERER,'http://www.google.ch/');
curl_setopt($ch,CURLOPT_TIMEOUT,10);
$html=curl_exec($ch);
if($html==false){
  $m=curl_error(($ch));
  error_log($m);
}
curl_close($ch);
return $html;
}

$html=getPage("http://www.webmaster-talk.com/");
$html=htmlentities($html);
echo $html;  

 

[mort]

the files themselves are not the problem, they work fine if I use

<script type='text/javascript' src='ajax.php'></script>

 

its only when I need to extract the js from that file into a string that it causes issues

 

also i understand what an exclusion list is, can you please explain how it applies to this situation? ta

 

Edit: Ahh curl, good idea!

[mort]

cheers bornecw just the trick

You could also just use file_get_contents on the full URL; like with cURL but only one line of code.
