PHP strange is_int behaviour

I have a form which is posting an array which looks like this:

Array
(
    [SearchForm] => Array
    (
        [query] => Eg: 2 Bedroom Flat Chelsea
        [rent] => 1
        [share] => 0
        [short] => 1
        [price_min] => 50
        [price_max] => 100
    )

    [yt0] => Search
)

I want to check if the value for $_REQUEST['SearchForm']['price_min'] is not empty, and is an integer. I am using:

if (($_REQUEST['SearchForm']['price_min'] != "") && (is_int($_REQUEST['SearchForm']['price_min']))){
    ...
}

The is_int is returning false (the if statement is not being executed) Any ideas why?

If the result comes from a posted html form, the value is most likely a string.

You can use is_numeric to check for a valid number string.

Because POST and GET parameters are always string, so instead of is_int use is_numeric

The value is probably "50" and not 50 (it's a string). Try is_numeric() instead of is_int().
