Searching Strings

[bpat1434]

Hello.

I'm trying to search a variable that was submitted, and find out if the user entered the @domain.com. I need to do this to decide whether or not to add the "@domain.com" to the string or not.

I've seen the eregi_replace and the strpos() functions, but not sure how to use them. Is there a simple search method that will look at a string and tell me whether or not the "@domain.com" is present?

Thanks for the help.

You could use [man]preg_match/man, with the idea that the name used would be alphanumeric and may have a dash after the first character.

A simple though incomplete example would be:

<?php
if (!empty($_GET['n'])) {
	if (preg_match('/(.*)\@[a-z0-9][a-z0-9\-]*\.(com|net|org)/i', $_GET['n'], $matches) == 1) {
		echo $matches[1];
	}
} else {
	echo '<a href="' . $_SERVER['PHP_SELF'] . '"?n=[e-mail]">[e-mail]</a>';
}
?>

Thanks for the help....

Though your way is very.... confusing....

I used the eregi() function to see if it would work.

Thanks for the help though.
