UBB.Developers Forums Community Development Programming PHP and Server-side Scripting truncating a string

hi

i believe theres a pattern-something command to do this, as theres no function to truncate a string based on its length (at least i couldnt find one...). so, huh... do you know how to make this?

thanks.

If I understand you correctly, substr will do that: http://perldoc.com/perl5.6.1/pod/func/substr.html

$name = substr($name, 0, 100);

what if the $name variable doesnt have a hundred characters? will it return the same string, or will it return an error?

thanks.

I don't know offhand. If the documentation doesn't cover that case, try it and see what happens.

If it doesn't work the way you want, you could check the length of the string first:

thanks alot.

What happenes why you try it???

The best way to learn is to try things first, then ask if you don't understand what happened

i dont know how to handle perl errors...

it would be something like this, i presume

$name = substr($name, 0, 100) or die "$!";

where the variable $! has the error message, or the error code, or 1/0 for error... O_o or even return the error for the $name variable, where one could print $name to see whats inside...
