You should try this:

if (is_int($request->input('public'))){


}

OR

if (is_numeric($request->input('public'))){


}

is_int() does not work in Lumen 6+ for inputs. It always says false, only is_numeric() works, but that does not have the same functionality – dodancs Feb 23 '20 at 20:24

filter_var($request->input('public'), FILTER_VALIDATE_INT) !== false

because:

is_int() is true for 12 but isn't for "12"
is_numerric() is true for 12.12312323

Use is_int:

$number = $request->input('public');

if (is_int($number)) {
   dd('number is an integer');
} else {
   dd('number is not an integer');
}

Data taken from the input is always a string.

Use Laravel validation to check if the data from the input is integer or number.

You can use ctype_digit

<?php
$cadenas = array('1820.20', '10002', 'wsl!12');
foreach ($cadenas as $caso_prueba) {
    if (ctype_digit($caso_prueba)) {
        echo "La cadena $caso_prueba consiste completamente de dígitos.\n";
    } else {
        echo "La cadena $caso_prueba no consiste completamente de dígitos.\n";
    }
}
?>

You can also use shorthand if:

$isInteger = (is_int($request->input('public'))) ? true : false;

Using the ternary operator like this is redundant because is_int() already only resolves to true or false. – aidangoodman7 Jul 15 '23 at 01:32
