Question

I am using this simple PHP script which fetches the shared resources, in this example tiny_mce. How can I extend this script so that it checks if a local copy exists first before fetching the file from the shared resource.

<?php
$request = $_SERVER['QUERY_STRING'];
$url = 'http://shared.domain.co.uk/javascript/' . $request;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);

$headers = substr($data, 0, strpos($data, "\r\n\r\n"));
$headers = preg_split('/\n|\r\n?/', $headers);
foreach($headers as $header)
    if(strpos($header, 'Content-') !== false)
        header($header);
$data = substr($data,strpos($data, "\r\n\r\n")+4);
print $data;
?>

I knew there was a reason, although it does run rather slow.

tinyMCE into 2 locations e.g:

Localhost

• /www/javascript/resources/tiny_mce

Shared subdomain

• /var/www/domain.co.uk/subdomains/shared/public/javascript/resources/tiny_mce

.php
small php script to be included with each project that uses tinymce e.g: “domain.co.uk/webapp/shared/javascript/resources/tiny_mce/jquery.tinymce.js”

<?php
$request = $_SERVER['REQUEST_URI'];
$request = substr($request, strpos($request, 'javascript/resources/')+21);

$domain = 'shared.domain.co.uk';
if(strpos($_SERVER['HTTP_HOST'], 'sandbox.') !== false) {
    $domain = 'sandbox.domain.co.uk';
} elseif(strpos($_SERVER['HTTP_HOST'], 'localhost') !== false || strpos($_SERVER['HTTP_HOST'], '127.0.0.1') !== false) {
    $domain = 'localhost';
} 

$url = 'http://'.$domain.'/javascript/resources/' . $request;

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);

$headers = substr($data, 0, strpos($data, "\r\n\r\n"));
$headers = preg_split('/\n|\r\n?/', $headers);
foreach($headers as $header)
    if(strpos($header, 'Content-') !== false)
        header($header);
$data = substr($data,strpos($data, "\r\n\r\n")+4);
print $data;
?>

Then a .htaccess script to rewrite anything after “resources” in: domain.co.uk/webapp/shared/javascript/resources

RewriteEngine On

RewriteRule (.*) index.php?%{QUERY_STRING}
