Removing minus signs (not working)

dougmcc1

How come this doesn't work?

$var=ereg_replace("[-]","",$var);

or this?

$var=ereg_replace("-","",$var);

I want to edit out minus signs in a particular field in my form but niether of the above works. Any ideas?

Thanks.

Hello again...

Maybe you'd have better luck with str_replace()?

$var=str_replace("-","",$var);

Hey - take a break 🙂

(after I get this working)

dougmcc1

Yep that works. Thanks once again.

LOL 😃

These guys helped me a great deal when I was learning. I'm just giving back.

Though....if you wanted to put my name on there.....I wouldn't object 😉

dougmcc1

Haha well I appreciate your help. I'll definately keep you in mind if I make anything off this site. And I better, or else I wasted 3+ months for nothing.

Yeah, you better remember me when you put Bill Gates outta business 😃

As stated, [man]str_replace/man is your friend (and, so is Lord Shryku, apparently) 😃.

The reason it doesn't work is because the hyphen delineates members of a class in POSIX Regexps. But, once again, ereg() is overboard.

If you were using numbers, you might try [man]abs/man.

No actually I found out why my statement wasn't working. Consider the following:

$var2=ereg_replace("-","",$var2);
$var2=ereg_replace(" ","-",$var1);

The first statement has no effect because the variable where the dashes are being removed from is being replaced with var1.

The correct code is:

$var2=ereg_replace("-","",$var1);
$var2=ereg_replace(" ","-",$var2);

I'm actually using ereg now instead of str_replace() to keep things consistent.

well, do what suits, but str_replace is much faster if you're concerned about speed 🙂

dougmcc1

Speed is good 🙂

Thanks for the tip.
