ereg_replace to preg_replace

[eevan79]

It seems to preg_replace is advisableto use instead of ereg_replace. I'm not sure how to swap this simple code with preg_replace:

$text = ereg_replace("[^0-9]", "", $text);

 

Is this correct?

$text = preg_replace("#[^0-9]#i", "", $text);

Technically the exact translation of that code would be...

 

$text = preg_replace("#[^0-9]#", "", $text);

 

The i modifier makes the match case insensitive, which ereg_replace isn't (that's what eregi_replace was for). Having said that, it's purely academic since you have nothing in your pattern that would be affected by case sensitivity.

what, you mean there's no such thing as lowercase numbers?
