how to use preg_match to check whole text

Question

Hi i have a problem with preg_match function.
i want to check whole text against pattern and return true if whole text matched with pattern and false for not matched or

Answer 1

Just change the pattern like this:

"/^[\d]+$/"

Remember that:

• ^: means the start of the string
• $: means the end of the string

Answer 2

You need to use ^ to indicate the start of the string and $ for the end

if (preg_match("/^[\d]+$/","99ab")) return true; 
else return false;
