How to Scan PHP Variables To Retrieve a Particular Value

[abhighat4214]

Hello all.
I wanted to ask a simple doubt. I am not so well versed with the syntax and semantics of PHP and I'm new to it.
I'm having the following code.
$var1="100 <" or $var1 = "> 100"
What I want to do is segragate the relational operator and the number into 2 separate variables.The relational operator can be on the left side of or on the right side of the number(there is no hard and fast rule regarding the position of it).Kindly guide me on how it's supposed to be done.

Thanking You all for your help

Heya, Abhighat.

To do this, you'll want to use regular expressions (http://regular-expressions.info):

[code=php]
preg_match('/(>?)(\\d+)(>?)/', $var, $matches);

$number = $matches[2];
$operator = (empty($matches[1]) ? $matches[3] : $matches[1]);
[/code]
