cURL is a command line tool for transferring files with a URL syntax, supporting FTP, FTPS, HTTP, HTTPS, GOPHER, TELNET, DICT, FILE, and LDAP. cURL supports HTTPS certificates, HTTP POST, HTTP PUT, FTP uploading, HTTP form-based upload, proxies, cookies, user+password authentication (Basic, Digest, NTLM, Negotiate, Kerberos, etc.), file transfer resume, proxy tunneling, and other useful tricks.
Here's how to use cURL in place of the PHP option allow_url_fopen:
Fetching a web page
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
?>
Alternative for file_get_contents()
Instead of:
$file_contents = file_get_contents('http://example.com/');
// display file
echo $file_contents;
?>Use this:
$ch = curl_init();
$timeout = 5; // set to zero for no timeout
curl_setopt ($ch, CURLOPT_URL, 'http://example.com');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
// display file
echo $file_contents;
?>
Alternative for file()
Instead of:
$lines = file('http://example.com/');
// display file line by line
foreach($lines as $line_num => $line) {
echo "Line # {$line_num} : ".htmlspecialchars($line)."
n";
}
?>Use this:
$ch = curl_init();
$timeout = 5; // set to zero for no timeout
curl_setopt ($ch, CURLOPT_URL, 'http://example.com');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
$lines = array();
$lines = explode("n", $file_contents);
// display file line by line
foreach($lines as $line_num => $line) {
echo "Line # {$line_num} : ".htmlspecialchars($line)."
n";
}
?>
