I'm having trouble checking if the value of $_GET is integer. Here is the code:
<?php
$modo=$_GET['PG'];
if(is_int($modo)){
echo "e inteiro";
}else{
echo "n e inteiro";
}
?>
Even though I put a number in $_GET , it always returns that it is not a int .
You can use the is_neric function of PHP that checks whether a variable is a number, even if it comes as a string.
But it has to be noted that it will check from Hexadecimal to Real and binary numbers as numeric TRUE
The HTTP GET method returns an array of strings passed by url through the function urldecode .
So I suggest other forms of verification, in case% of% is a number:
if(is_numeric($_GET['PG']))
Or even only if the desired variable exists, using $_GET['PG'] , which for paging also works perfectly:
if(isset($_GET['PG']))
In this case
$_GET['PG']
It returns a string so it is always false ...
