alternative to strlen()

[LordShryku]

Hi everyone,
I'm trying to find an alternative to strlen(), and I'm wondering if someone can help....

I'm doing a select nextval('sequence') from a database and I need it to determine the exact string length and add the appropriate letter. Like...

if(strlen($num) = 1) {
$finalnum = "abc"."$num";
}
if(strlen($num) = 2) {
$finalnum = "ab"."$num";
}
if(strlen($num) = 3) {
$finalnum = "a"."$num";
}

Problem is that strlen() doesn't work with the "=". Anyone know another way to do this or maybe a way around this?

Thanks!

It does work with strlen(), you just forget to use == instead of =.

if(strlen($num) == 1) {
$finalnum = "abc"."$num";
}
..

if(strlen($num) = 1) {
$finalnum = "abc"."$num";
}
if(strlen($num) = 2) {
$finalnum = "ab"."$num";
}
if(strlen($num) = 3) {
$finalnum = "a"."$num";
}

In fact the problem is that you're trying to define strlen($num) instead of evaluating it.

It's a common mistake I always do 😉

Try using this:

<?
if(strlen($num) == 1) {
$finalnum = "abc"."$num";
}
if(strlen($num) == 2) {
$finalnum = "ab"."$num";
}
if(strlen($num) == 3) {
$finalnum = "a"."$num";
}

?>
