Getting HTTP code in PHP using curl

Question

I m using CURL to get the status of a site  if it s up down or redirecting to another site  I want to get it as streamlined as possible  but it s not working well    lt  php  ch   curl init  url   curl setopt  ch CURLOPT RETURNTRANSFER 1   curl setopt  ch CURLOPT TIMEOUT 10    output   curl exec  ch    httpcode   curl getinfo  ch  CURLINFO HTTP CODE   curl close  ch    return  httpcode    gt    I have this wrapped in a function  It works fine but performance is not the best because it downloads the whole page  thing in if I remove  output   curl exec  ch   it returns 0 all the time   Does anyone know how to make the performance better

First make sure if the URL is actually valid  a string  not empty  good syntax   this is quick to check server side  For example  doing this first could save a lot of time   if   url     is string  url       preg match    http s        a-z0-9-     a-z0-9-       0-9             i    url        return false      Make sure you only fetch the headers  not the body content    curl setopt  ch  CURLOPT HEADER    true       we want headers  curl setopt  ch  CURLOPT NOBODY    true       we don t need body   For more details on getting the URL status http code I refer to another post I made  it also helps with following redirects     How can I check if a URL exists via PHP      As a whole    url    http   www example com    ch   curl init  url   curl setopt  ch  CURLOPT HEADER  true         we want headers curl setopt  ch  CURLOPT NOBODY  true         we don t need body curl setopt  ch  CURLOPT RETURNTRANSFER 1   curl setopt  ch  CURLOPT TIMEOUT 10    output   curl exec  ch    httpcode   curl getinfo  ch  CURLINFO HTTP CODE   curl close  ch    echo  HTTP code       httpcode

curl exec is necessary   Try CURLOPT NOBODY to not download the body   That might be faster
