echo javascript code returned by curl

Question

I make a curl Request to get some Javascript Code back. When i execute the php in terminal, i get the Javascript code. But when i try it with a browser the javascript code is not shown.

I tried to echo it with json_encode. But i only get a false back. I also tried here doc. but nothing seems to work.

Maybe because the javascript code i get back starts like this:

 !function(n,t,d){function e(n,t){

How can i echo this javascript code for browser. In terminal it works fine.

<?php
        function getUrlCurl($url) {
            $curl_handle = curl_init();
            curl_setopt ($curl_handle, CURLOPT_URL, $url);
            curl_setopt ($curl_handle, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt ($curl_handle, CURLOPT_CONNECTTIMEOUT, 1);
            $buffer = curl_exec($curl_handle);
            $info = curl_getinfo($curl_handle);
            curl_close($curl_handle);
            return $buffer;
    }


$response = getUrlCurl(myUrl);
?>
<html>
<head>
<script>
<?php echo json_encode($response); ?>
</script>
<body>
</body>
</html>

Could you please share some PHP code related to curl requesting and printing the code? A minimal case would help others to reproduce the problem. — FelisCatus, Sep 07 '15 at 10:39
What HTML do you get when you run the PHP. Look at the source code in your browser. What do you expect to get? Why aren't you just using ``? — Quentin, Sep 07 '15 at 10:48
the company that wants me to put their code in our site has some restrictions. i cannot put the code in an script src. they want me to echo it in an script tag — ah75, Sep 07 '15 at 10:49
If you only see `false` as the result, then the curl execution has failed. Please follow the answer in http://stackoverflow.com/questions/3757071/php-debugging-curl and get more verbose log. Then you can add more information in the original question. — FelisCatus, Sep 07 '15 at 11:01
And also fopen is not allowed on our servers. So that's the reason i have to make a curl request. so, no file_get_contents allowed. — ah75, Sep 07 '15 at 11:02
no, the curl execution has not failed. as i said, it works when i execute the php file in terminal. i get the response i expect in terminal. — ah75, Sep 07 '15 at 11:04
But it can fail in browser even if terminal works. It can be due to different configurations or environments. When in doubt, check the log to trace the request. — FelisCatus, Sep 07 '15 at 11:06
@FelisCatus: you were right. it was the proxy server. thank you :) — ah75, Sep 07 '15 at 11:53
@ah75 Could you please share your knowledge with others by kindly adding an answer with code about the proxy settings? You can mark it as accepted. — FelisCatus, Sep 07 '15 at 12:02

This may be over simplifying things, but you could try something like this;

<?php
    $response = file_get_contents(myUrl);
?>
<html>
    <head>
        <script>
            <?php echo $response; ?>
        </script>
    </head>
<body>
</body>
</html>

Also, it may be worth mentioning, that in your code sample, there is no closing <head> tag. That could also be causing you to have issues.
