More concise way to check to see if an array contains only numbers (integers)

[durga182]

How do you verify an array contains only values that are integers?I'd like to be able to check an array and end up with a boolean value of \[code\]true\[/code\] if the array contains only integers and \[code\]false\[/code\] if there are any other characters in the array. I know I can loop through the array and check each element individually and return \[code\]true\[/code\] or \[code\]false\[/code\] depending on the presence of non-numeric data:For example:\[code\]$only_integers = array(1,2,3,4,5,6,7,8,9,10);$letters_and_numbers = array('a',1,'b',2,'c',3);function arrayHasOnlyInts($array){ foreach ($array as $value) { if (!is_int($value)) // there are several ways to do this { return false; } } return true;}$has_only_ints = arrayHasOnlyInts($only_integers ); // true$has_only_ints = arrayHasOnlyInts($letters_and_numbers ); // false\[/code\]But is there a more concise way to do this using native PHP functionality that I haven't thought of?Note: For my current task I will only need to verify one dimensional arrays. But if there is a solution that works recursively I'd be appreciative to see that to.
