IS_INT(3) 1 IS_INT(3)is_int - Find whether the type of a variable is integerSYNOPSIS
bool is_int (mixed $var)
DESCRIPTION
Finds whether the type of the given variable is integer.
Note
To test if a variable is a number or a numeric string (such as form input, which is always a string), you must use is_numeric(3).
PARAMETERS
o $var
- The variable being evaluated.
RETURN VALUES
Returns TRUE if $var is an integer, FALSE otherwise.
EXAMPLES
Example #1
is_int(3) example
<?php
$values = array(23, "23", 23.5, "23.5", null, true, false);
foreach ($values as $value) {
echo "is_int(";
var_export($value);
echo ") = ";
var_dump(is_int($value));
}
?>
The above example will output:
is_int(23) = bool(true)
is_int('23') = bool(false)
is_int(23.5) = bool(false)
is_int('23.5') = bool(false)
is_int(NULL) = bool(false)
is_int(true) = bool(false)
is_int(false) = bool(false)
