Subject: [PHP] ereg-digits only...
How do I check a string for it to only contain numbers?
if(!ereg(([0-9]+),$string)){
print It contains characters other than numbers;
}else{
print Only numbers;
}
Can anyone give some feedback...
regards,
Bart

Why not use the RE's? I usually use preg_* so I'll give the example
using these...
if (preg_match (/^\d+$/, $string)) {
print (Yep... Only digits.);
} else {
prnt (Noop! There are non-digit characters...);
}

RE: [PHP] ereg-digits only...
That wouldn't work!
1) You meant to write: if (((int)$string==$string) ($string0))
2) (int)'5a' == 5, so this formula would result is 5a == 5!
