[jonno946]

How can i detect if the string contains spaces? I want to make it so ursers can not have spaces.

just parse the string into seperate variables and then check each one for spaces, if one has a space, go to all the ones after it and change them to one variable forward. then delete the last one. this will take all spaces out. There may be an useful function that does this for you but I don't know of it, and neither do you probably.

There's many way to do it, depending of what
you want to do exactly ;

for instance, using the strstr() function :

$string = "PHP";
$container = "I love writing PHP code.";

if (strstr($container,$string))
{
echo "found it.";
}
else
{
echo "not found.";
}

<?
$string = str_replace (' ', '', $string);
?>

you don't even have to check for spaces first, this code will strip them out anyway
