Re: [PHP] ereg_replace help
From: Richard Davey [EMAIL PROTECTED]
I'm sure this is blindingly simple, but could anyone tell me how to
get an ereg_replace() to return a string where all characters OTHER
than alpha-numerics have been stripped out?
$output = ereg_replace('[^a-zA-Z0-9]','',$string);
The ^ is NOT (when the first character in a bracketed character set). So
anything NOT alphanumeric is replaced.

I can do the reverse with:
$output = ereg_replace('[[:alnum:]]', '', $string);
Which will happily remove all alpha-numeric characters from $string!
But I want it to remove anything but.. suggestions please?
did you try
$output = ereg_replace('[^[:alnum:]]', '', $string);
?

You can't use ! because it's not a valid special character in regular
expressions. It's really hard to craft do-not-match-this-word patterns.
You're better off separating the two pieces of logic.
$arr = array(
abcd - rst,
abcd - uvw,
abcd - xyz,
foobar - rst,
blah - rst,
googol - uvw
);
reset($arr);
while (list($key, $value) = each($arr))
{
if (substr($value, 0, 5) != 'abcd ')
{
$arr[$key] = ereg_replace('^(.*) - .*$', '\1', $value);
}
}
print_r($arr);

How do you mean its part of your code library? I would strongly
suggest using preg_* for its speed and capabilites.

thanks for everyone's help...
How do you mean its part of your code library?
I mean that the function I'm having to call is passed an array (coming from
a databse) and it has an option to do an ereg_replace() on the incoming
array. Due to the amount of other code relying on it, is very hard to change
without causing something strange to happen elsewhere :(
If all the code was mine, then I wouldn't have any reservations on changing
it in an instant. I'm having to improve the code gradually (good luck to me)
