Hello,
I am just learning the code igniter and i am in part with FORM validating. In document is written that we can use in parametr every function with 1 parameter.
I was searching the min_length function in php.net and there isn't this function, so it's some personal Code Igniter function ? Is there any list of CI personal functions ?
Is working function length ? When we just want only 5 digits in form so can i use function is_numeric ?
Thanks for help
