Validation Functions Validation functions are those that come handy when validating data.bool isEmail ($emailID) Returns true if it is valid email ID or false if not. e.g. echo 'Your email ID is ' . ( isEmail ($myEmail) ? 'valid' : 'invalid' ); bool isNull ($var) Returns true if null or not assigned a value, or false if value is assigned. e.g. echo isNull($stream) ? 'No stream is selected' : $stream . 'is your stream'; bool isString ($text) Returns true if it is a text, or else false. e.g. echo isString ($text); bool isNumber ($number, [$allowIntOrFloatVals]) Returns true if it is a positive number. If second parameter is set true, then the number is checked against float and integer values (positive and negative). e.g. echo 'The reference number entered is ' . ( isNumber ($myEmail) ? 'valid' : 'invalid' ); echo 'The math integer entered is ' . ( isNumber ($myEmail, true) ? 'valid' : 'invalid' ); |
