The PHP is_numeric() function can be used to find whether a variable is numeric. The function returns true if the variable is a number or a numeric string, false otherwise.
$x = 5985; var_dump(is_numeric($x));
//true
$x = "5985"; var_dump(is_numeric($x));
//true
$x = "59.85" + 100;
var_dump(is_numeric($x));
//true
$x = "Hello"
var_dump(is_numeric($x));
//false
