i'm new to php i tried to check if age is valid or not, i used the ereg function it displays the result fine but there is an error Deprecated: Function ereg () is deprecated in D:\wamp\www\functions\index.php on line 5, I don't know how to fix it.
I tried preg_match instead of ereg but it doesn't work it gives me error preg_match (): Unknown modify '?'
<?php
$modele = "^[0-9]?([0-9]?)$";
$age = "848";
if(preg_match($modele,$age)){
echo "age is valide <br>";
return true;
}else{
echo "age is invalide <br>";
return false;
}
?>
