Regex Google Publisher Code

What would the regex be in PHP to make sure a phrase is a Google Publisher code and not anything else?

Like...
"pub-1234567890123456"

 

Why would it be anything else ? can you explain further what your trying to achieve.

 

I want the Regex to make sure the inputted text is a Google Publisher Code and not some random numbers or letters or something.

 

There is no know way to check if a publishers ID is valid or not, so I suggest you use a numbers only (16) validation check on your input, thus use the text pub- within your scripts, as above though, this could still be a random 16digit number, theres no way to check that its a valid publishers id, only to manually try it.

 

its very easy but i cant do it
because iam bad in Regex

 

Here you go, I created alittle function for you:

The regex: #^pub-[0-9]{16}$#

<?php

function google_pub($pub)
{
$validate = preg_replace('#^pub-[0-9]{16}$#', "", $pub);

if(empty($validate))
	{
	return true;
	}
	else
	{
	return false;
	}
}

//1 = valid, 0 = not valid
echo(google_pub("pub-1234567890123455"));

?>
