[SOLVED] Extract only number

[timmah1]

If I have a variable in the database like this

83&sports=nfl

 

How can I show just the number and not the rest of the stuff.

This will always show a number and the &sports= whatever sport, the number could be in the hundreds

 

Thanks in advance

Putting aside the bad DB design.

 

<?php
$str = '83&sports=nfl';
$parts = explode('&', $str);
echo $parts[0];

Wasn't my design, just trying to get it working better.

 

Would this work as well?

$string = ereg_replace("[^0-900]", "", $favorite);

I don't find the need of regular expression for this because they're more intensive than necessary, but if you really want it...

 

<?php
$str = '83&sports=nfl';
preg_match('#^(\d+)#', $str, $match);
echo $match[0];

 

preg > ereg.

preg > ereg.

 

To elaborate. As of PHP6 ereg is depreciated. Also preg tends to be more universal since it users perl regular expressions. I would avoid using ereg due to the fact it is depreciated.
