I am trying to fetch contents of a url using the curl library in php. I have written the below code to do this. Even though I'am not getting an error in the code, nothing is being printed in the output. As there is no error message being displayed, I'm not able to figure out what I'm doing wrong. I'm trying to print details of url response like headers, body, time, size, errors (if any). I'm using xampp to run the below code.
<?php
function url_get_contents($url="google.com",$useragent='cURL',$headers=false,
$follow_redirects=false,$debug=false) {
# initialise the CURL library
$ch = curl_init();
# specify the URL to be retrieved
curl_setopt($ch, CURLOPT_URL,$url);
# we want to get the contents of the URL and store it in a variable
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
# specify the useragent: this is a required courtesy to site owners
curl_setopt($ch, CURLOPT_USERAGENT, $useragent);
# ignore SSL errors
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
# return headers as requested
if ($headers==true){
curl_setopt($ch, CURLOPT_HEADER,1);
}
# only return headers
if ($headers=='headers only') {
curl_setopt($ch, CURLOPT_NOBODY ,1);
}
# follow redirects - note this is disabled by default in most PHP installs from 4.4.4 up
if ($follow_redirects==true) {
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
}
# if debugging, return an array with CURL's debug info and the URL contents
if ($debug==true) {
$result['contents']=curl_exec($ch);
$result['info']=curl_getinfo($ch);
}
# otherwise just return the contents as a variable
else $result=curl_exec($ch);
# free resources
curl_close($ch);
# send back the data
return $result;
}
?>
