if Variable contains...

[Anon]

This is probably a simple question but I totally have no clue how to do this.

I want to check a variable and see if it contains a < in it. If it does, then i want to perform something. if it doesnt then i want it to do something else.

So here is an example:

$variable = 'here it < is';

if ($variable == ?????) { do this }
ELSE { do that }

Any ideas how to figure out if a string contains something in specific?

if(preg_match("/</", $variable))
do_something;
else
do_something_different;

Oh, that is an easy one. Here you go:

<?php
$variable = 'here it < is';

if(ereg("<", $variable)){ //Code for older ereg() function
print "Yes! '<' was found in \$variable";
}
else {
print "Sorry, '<' was not found in \$variable";
}

if(preg_match("/</", $variable)){ //Code for newer preg_match() function
print "Yes! '<' was found in \$variable";
}
else {
print "Sorry, '<' was not found in \$variable";
}

?>

And that's it!
