I’m building a web form in php, and while at testing the code, it is not showing the correct way, that I wanna.
I mean to say
It is showing integer value as false, as an example
$int = 011;
$int2 = !is_int($int);
echo $int2;
it is showing this result as 1, but only when I enter the value through form with post method.
While if I test the same in another script without post and form processing then it is working fine.
So, I wanna know why it is showing such weired behavior ?
Here is the full code of my form:
<?php
require_once "includes/functions.php";
require_once "database.php";
if(!loggedin())
{
header("Location: login.php");
}
if($_GET == false)
{
$user = $_SESSION['NORMAL_USER'];
$uid = $_SESSION['USER_ID'];
echo $uid;
echo "<br />";
}
if($_POST)
{
if(htmlCheck($_POST))
{
echo "<meta http-equiv=refresh content=4>";
$message = htmlCheck($_POST);
}
else
{
$expected = array('PAN', 'mobile', 'std', 'fone', 'father', 'day', 'month', 'year', 'flat', 'area', 'town', 'state', 'PIN');
$required = array('PAN', 'mobile', 'std', 'fone', 'father', 'day', 'month', 'year', 'flat', 'area', 'town', 'state', 'PIN');
$missing = array();
$error = array();
foreach($_POST as $key => $value)
{
$temp = is_array($value) ? $value : trim($value);
//if empty and required, add to $missing array
if(empty($temp) && in_array($key, $required))
{
array_push($missing, $key);
} // otherwise, assign to a variable of the same name as $key
elseif(in_array($key, $expected))
{
$temp = mysql_real_escape_string(htmlentities(strip_tags($temp)));
${$key} = $temp;
}
}
echo "<pre>";
print_r($_POST);
print_r($missing);
echo "</pre>";
echo "<hr />";
echo "$std";
echo "<br />$fone<br />";
$int = !is_int($std);
echo $int."<br />";
$int1 = !is_int($fone);
echo $int1."<br />";
$int3 = !is_int($std) || !is_int($fone);
echo $int3."<br />";
if(empty($missing))
{
if(strlen($PAN) != 10)
{
$message = "You have not entered the correct value for PAN Number. Please rectify it.";
//array_push($error, $message);
}
elseif(!is_numeric($mobile) || strlen($mobile) != 10)
{
$message = "You have not entered the correct Mobile No.";

}
elseif(!filter_var($state, FILTER_SANITIZE_STRING))
{
$message = "You have not entered the correct value for the state";
}
elseif(!is_int($PIN) && strlen($PIN) != 6)
{
$message = "Please provide the correct PIN CODE of your area which should be of 6 digit only.";
}
else
{
$date = "$year-$month-$day";
$phone = "$std-$fone";
$sql = "insert into userinfo(uid, PAN, DOB, mobile, phone, father, flat, area, town, state, pin) ";
$sql .= "values('$uid', '$PAN', '$date', '$mobile', '$phone', '$father', '$flat', '$area', '$town', '$state', '$PIN')";

if($res)

}
