is numeric

[aspen]

Whats a good way to test to see if a variable contains only numbers, or text.

I got one variable, and I got to do something different with it depending on whether or not it contains text or numbers.

I think is_numeric() does what you're looking for.

And people still ask.. "Perl or PHP for the web?"


Perl version: if ($string=~/(0-9*)/g)

PHP version if (is_numeric($string))




I love PHP! (ps. my perl regexp might be bunk :-)

Yeah, PHP is nice, but what are the advantages Perl has over PHP? I know php makes it easy to do the hard things with perl but it also makes some of the easy things with perl hard with PHP.

So basically what I'm asking is what should I learn about perl? I'm just a PHP guy. But I want to learn things in other languages that I can't do with PHP. I know a bit of javascript, but then the tutorial started getting into the real scripting and if statements and stuff. So I stopped there because I knew how to do that with PHP.

Well I found that PERL is way better for doing mundane server admin tasks, like manipulating files, etc.. especially when invoked from the commandline. But PHP is definitely better for the web stuff.

I found PERL excellent at file manipulation as freddu said, and it is awesome if you are going to create a webadmin control panel for a website.... because it is more of a true programming language then PHP, it has abroader spectrum of usefullness. Both are wonderfull in their respective fields of use.
