Two PHP Functions to Check HTTP Response Code (Status) of a URL using Curl

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.

<?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:

apt install php-curl

Example usage:

<?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”

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;
    }
}
