A simple problem i need a little help with

[AliasZero]

Hi there, i need to do this in php:

I have some strings. some have numbers like 18.5 and 4 in them, others have a number and then a b after it. for example my strings might be

$a = '18.5';
$b = '6';
$c = '21.9b';
$d = '3.5b';
$e = '7';

how would i be able to check, say $c and see if it contains a "b" or not?

Thanks for your time.

$a = '18.5';
$b = '6';
$c = '21.9b';
$d = '3.5b';
$e = '7';

if (substr($b,strlen($b)-1,1)=="b") {
echo("b");
}

If you could have a 'b' in any other place you could just search for it in the variable with stristr
