Testing a string with PHP

Question

I am looking to run a test on a string to determine whether or not it meets certain condiditions. I would like to extract the last 4 characters of any given string and test them against a constant variable. Any Ideas on how to do this?

Ex:

[email protected]

I would like to know if the last four characters in the string are '.edu'

Thanks

are you dealing with only emails ?

You can use substr for single-byte and mb_substr for multi-byte strings:

$suffix = substr($str, -4);

The negative start parameter value specifies to start from the end of the string.

Depending on your needs, any of the following might work for you:

strrpos() - find last occurrence within a string
substr() - check the contents of a specific portion of a string
preg_match() - complex pattern matching
