[PHP] ICQ # validation
if(ereg(^[0-9]{7,9}$, $_REQUEST[icqnumber])) {
print(a-okay!);
} else {
print(error msg);
}
Although I'm not too familiar with regexp I'd say the code validates
because the icq number you are providing actually confimrs to the pattern.
The first seven to nine digits contain only numbers so the pattern is
true. Th ce pattern does not check the length of your provided string.
If I'm correct than 123456789 This is a test will also proof to be
correct. So you have to do two things first check the whole argument for
digits like ereg('^[0-9]{'.strlen($_REQUEST['icqnumber']).'}',
$_REQUEST['icqnumber']) and check length separatly. (U can also use
[[:digit:]]) Or use the code as mentioned before.
In your place I would not assume anything about the length of the icq
number.
Hope that helps
Stefan
P.S.: Please correct me if I'm wrong with the above
Re: [PHP] ICQ # validation
Well ...
- the {7,9} means that the previous char/group should repeat 7 to 9 times
...
- ^ means the beginning of the string
- $ means the end of the string
So everything, that validates, is 7 to 9 numbers.
123456789 This is a test won't validate - it contains chars instead of $
(end of string) after [0-9]{7,9} = 7 to 9 numbers.
And yes, you can use something like [[:digit:]] but I must admit I don't use
that much.

Re: [PHP] ICQ # validation
Also, don't forget to escape the $ character in your expression, since it is
reserved for variable declaration.

[PHP] ICQ # validation
Maybe I'm off my rocker, but I don't see how this can't work. I'm trying to validate
an ICQ number, and assuming a valid one is between 7 and 9 numbers. My line of code is
this:
if(ereg(^[0-9]{7,9}$, $_REQUEST[icqnumber])) {
print(a-okay!);
} else {
print(error msg);
}
I've submitted the ICQ # 2264532680, but it validates. Any ideas?
Re: [PHP] ICQ # validation
Use single quotes around your pattern.
if(ereg('^[0-9]{7,9}$',...
With the double quotes, PHP is probably seeing the $ and looking for a
variable, even though it's at the end of the string.

if (ereg (^[0-9]{7,9}$, 2264532680)) {
print (a-okay!);
} else {
print (error msg);
}
fails. I suspect you're not grabbing the variable from the environment
correctly.

Re: [PHP] ICQ # validation
Does it actually NEED a regexp?
UNTESTED code:
?
$icq = 2264532680;
if( (is_int($icq)) (strlen($icq) 7) (strlen($icq) 9) ) {
echo yah;
} else {
echo nah;
}
?
FWIW, Are you SURE that all valid ICQ #'s are between 7 and 9 chars?
Surely at some point they'll reach 10 chars, and *may* have started at 6?

Would be kinda cool if your scirpt did a search on icq.com and if it
found a result then the ICQ # is valid.. of course that means you're
relying on the icq server to be up and the search page to stay
consistant..
