Hello,

klingt fast genauso bequem, wie file_get_contents().

Ist cURL innerhalb PHP auch so leisgtungsstark, wie standalone?
Wie kommt man da an die Ergebnisse der einzelnen Stufen?

Setze die Curl-Option CURLOPT_VERBOSE auf true:

<?php 

$dst_url = 'https://www.example.com';

header( 'Content-Type text/plain' );

error_reporting( E_ALL );
ini_set( 'display_errors', 1);

$ch = curl_init();

curl_setopt( $ch, CURLOPT_URL, $dst_url );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt( $ch, CURLOPT_CUSTOMREQUEST, 'HEAD' );
curl_setopt( $ch, CURLOPT_NOBODY, true );


### So geht das:###
curl_setopt( $ch, CURLOPT_VERBOSE, true ); 

$result = curl_exec( $ch );

print_r( curl_getinfo( $ch ) );

curl_setopt( $ch, CURLOPT_VERBOSE, true );

Die zusätzlichen Ausgaben sind dann:
