How do you validate the numeric values with Hypen's (-) ? I just want to validate the numeric value with Hypen's and without Hypen's. Thank you so much !

For example 555 or 5-55

CodePudding user response：

You may use preg_match with the regex pattern ^[0-9-] $:

$input = "867-5309";
if (preg_match("/^[0-9-] $/", $input)) {
    echo "MATCH";  // prints MATCH
}
