Validating a website in PHP - Anthony Shapley

I found this pretty hard to begin with I was uncertain of how to check whether a website was online without writing a complicated string of Regular Express and even then this didn’t check if the site was active at that point in time. The solution was supprisingly simple:

We can use the PHP Function “fsockopen” to check that a the port is open on the appropriate hostname (website address).

$urlExists = @fsockopen($siteurl,80);

if($urlExists) {

// do something

} else {

// show an error

}

Simply pass in the Site URL Variable.
