* for php numbers

$key = str_replace("width="numbers"", "", "$key");

i'd like to do search & replace for width="numbers"

is there has something like "(*)" instead of all numbers?

thank you

 

I believe the following will work:

is_numeric();

 

Is is_numeric(); for check whether numbers?

i am already know that are numbers.

thank you

 

I think you need preg_replace

 

He/She is right... I remember now

 

echo preg_replace('#(?<=width\=)(\'|")(\d+)(\\1)#misux','$1$1',$key)."\n";
