Determining variable type of POST VARS

[Anon]

Is there a way to determine if the type of variable from a http post var is (int, string, array).. I have tried alot of stuff allready.. here is what i have so far:

if (is_int($var)) {
echo 'is int';
} elseif (is_array($var)) {
echo 'is array';
} elseif (is_string($var)) {
echo 'is string';
}

it detects wether or not its an array but unfortunalty it will not distinguish between int || string... I have no idea what is the problem.. maybe some sort of php thing where all ints upon being posted to the server get casted as strings...???? any help would be much appreciated

Thank you in advance

Well i guess i didnt RTFM too well.. i found the function 'gettype()'. but it still had problems distinguishing between strings || integers... so i did:

switch(gettype($var)):
case "string":
if (is_numeric($var)) {
echo 'is int';
} else {
echo 'is string';
}
break;

case "array";
echo 'is array';
break;
endswitch;

but now i sit back after i just wrote that and think the best way would be...

if (is_array($var)) {
echo 'is array';
} elseif (is_numeric($var)) {
echo 'is int';
} elseif (is_string($var)) {
echo 'is string';
}

thats what i have come up with and it works... still looking for something a bit cleaner though... that seems a bit dirty... any light you can shed on this would be helpful

thanks in advance

you can try this

if(!ereg('[A-Za-z]+', $posted_variable))
echo"string";

to do so for numbers you can use the same function.
Above function is more of a validation kind of function.

Hope it helps!
