how do I search for the following symbols in the [B]first[/B] position of a variable and if not found insert a “=” ?

[QUOTE]

=, !=, <>, < and >

[/QUOTE]

$category=”<32″ would be ok (as would >32, <>32, =32 or !=32 )

but if $category=”32″ then change $category to be”=32″

@pyroSep 08.2003 — Try something like this:

[code=php]<?PHP
$category = "32" ;
if (!preg_match("/^=|!=|<>|<|>/",$category)) {
$category = "=".$category;
}
echo $category;
?>[/code]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.
