[SOLVED] is_int() function?

[thefollower]

When can this ever be used in php? Because when i input 10 in a input box im assuming php takes it as a string of two chars which is 1 and 0 rather than the number 10 which would explain why my is_int() function check fails when it checks if the input is an integer... so what can i do to check the number is a nice integer?

 

This is what i put:

<?php
$Price = mysql_real_escape_string($_POST['Price']);
If($Price < 1 OR !(is_numeric($Price)) OR !(is_numeric($Tokens2))
OR !(is_int($Price))){
?>
Price must be greater than zero!</span>
<br>
<a href="test.php">Back</a>
<?
}
?>

Use ctype_digit() instead.

Thank you

Note you should type cast the var since it only accepts strings. 

 

ctype_digit( string $int )

ctype_digit( string $int )

 

In his case it will always be a string, but sure, to stay out of trouble later on.

ctype_digit( (string)$int );
