eregi

[STooPID]

well i know that that the eregi function searches a string for certain characters, well i was just wondering if theres away for like.....

if (there is anything BUT theese characters) { blah, blah blah };

you know wut i mean?
can anybody help?

Use the ! operator...

if (eregi("z", $string)) {
    echo "'$string' contains a 'z' or 'Z'!";
}

(If the string contains a Z)

if (!eregi("z", $string)) {
    echo "'$string' contains anything other than a 'z' or 'Z'!";
}

(If the string doesn't contain a z, implies it contains anything other than a z)

When you do this, you kind of have to think backwards in your conditional actions too, but it's one way to do it.

exactly what i wanted, thanks man

EDIT: nevermind, that aint what i was looking for

ok, ill explain it a little differntly...i have a text field....and when it is submitted, i want it to only beable to contain numbers or else the user gets a message....is there a way to do that?

[LordShryku]

if(eregi("[^a|k|s|z]", $text)) {
   echo "field can only contain a, k, s, or z";
}

If you only want numbers, you could just us [man]is_numeric[/man], [man]is_float[/man], [man]is_int[/man], or [man]ctype_digit[/man]. There's more than that, but should give you what you need :p
