System Call on PHP

Having a bit of problem with this. Script A calls/includes Script B. Script B has to execute a system call and return to Script A. Fails in flames. When I call 开发者_运维问答Script B on its own, it works just fine, I cannot for the life of me get it to work by calling it on A. Ive already tried

• Including it on A
• Calling it with another system call within A
• Making a bash script that calls B and then calling that bash script with A (I N C E P T I O N)

What are my options here?

Edit for code:

<?php
//B.php
//works fine when called on its own
function readsite ($url)
{
      $output=system("curl -ks $url");
      return $output;
}
?>


<?php
//A.php
include_once("B.php");
$url="www.google.com";
$read=readsite($url);
echo $read;
?>

I assume that the problem you are trying to solve here is fetching the contents of a website.

Give the following a try:

function readsite($url) {
    $ch = curl_init();
    curl_setopt($ch,  CURLOPT_URL, $url);
    curl_setopt($ch,  CURLOPT_RETURNTRANSFER, true); 
    $result = curl_exec ($ch); 
    curl_close($ch);
    return $result;
}

The curl extension provides you with a relatively sane and stable way to fetch stuff in php. Look at the docs for more information

This assumes availability of the php-curl extension though.

And of course (as lonesomeday pointed out) you should add the scheme to the url (use 'http://www.google.com' as url).
