Check the HTTP Reponse Status Code of a Request in PHP
We can use the following PHP function to send a request to the URL and get its HTTP status code.
1 2 3 4 5 6 7 8 9 10 11 | <?php if (!function_exists("get_http_code")) { function get_http_code($url) { $handle = curl_init($url); curl_setopt($handle, CURLOPT_RETURNTRANSFER, TRUE); $response = curl_exec($handle); $httpCode = curl_getinfo($handle, CURLINFO_HTTP_CODE); curl_close($handle); return $httpCode; } } |
<?php
if (!function_exists("get_http_code")) {
function get_http_code($url) {
$handle = curl_init($url);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, TRUE);
$response = curl_exec($handle);
$httpCode = curl_getinfo($handle, CURLINFO_HTTP_CODE);
curl_close($handle);
return $httpCode;
}
}It is based on the CURL library – which you can install using:
1 | apt install php-curl |
apt install php-curl
Example usage:
1 2 3 | <?php echo get_http_code("https://helloacm.com"); // print 200 ?> |
<?php
echo get_http_code("https://helloacm.com"); // print 200
?>Another implementation is to shell execute (basically run/shell_exec the command curl in the shell e.g. /bin/bash). The -I means to retrieve the HTTP Headers only, and the -s means to disregard other meta information. Then we just have to extract the first line of the headers e.g. “HTTP/2 200”
1 2 3 4 5 6 7 8 | if (!function_exists("get_http_code")) { function get_http_code($url) { $cmd = trim(shell_exec("curl -s -I \"$url\" | head -1")); list($http, $code) = explode(" ", $cmd); echo "$http and $code\n"; return (int)$code; } } |
if (!function_exists("get_http_code")) {
function get_http_code($url) {
$cmd = trim(shell_exec("curl -s -I \"$url\" | head -1"));
list($http, $code) = explode(" ", $cmd);
echo "$http and $code\n";
return (int)$code;
}
