PHP FILTER_VALIDATE_INT Filter

PHP Filter Information

Definition and Usage

The FILTER_VALIDATE_INT filter validates the value as an integer.

  • Name: "int"
  • ID-number: 257

Possible options or flags:

  • min_range - Specifies the minimum integer value
  • max_range - Specifies the maximum integer value
  • FILTER_FLAG_ALLOW_OCTAL - Allows octal numbers
  • FILTER_FLAG_ALLOW_HEX - Allows hexadecimal numbers

Tips and Comments

Note:When specifying options in an array, the options must be stored in an associative multidimensional array named "options". See the following example.

Example

<?php
$var=300;
$int_options = array("options"=>

var_dump(filter_var($var, FILTER_VALIDATE_INT, $int_options));
?>

Output:

bool(false)
