search and replace

[esm]

how do I search for the following symbols in the first position of a variable and if not found insert a "=" ?
=, !=, <>, < and >
$category="<32" would be ok (as would >32, <>32, =32 or !=32 )

but if $category="32" then change $category to be"=32"

Try something like this:

<?PHP
$category = "32" ;
if (!preg_match("/^=|!=|<>|<|>/",$category)) {
$category = "=".$category;
}
echo $category;
?>What the regexp does is check if the variable starts with any of the characters, and if it does not (due to the ! at the beginning of our if statement) it will concatenate a = to the beginning of the string.
