Check string length in PHP

Question

I have a string that is 141 characters in length. Using the following code I have an if statement to return a message if the string is greater or less than 140.

Answer 1

An XPath solution is to use:

string-length((//div[@class='contest'])[$k])

where $k should be substituted by a number.

This evaluates to the string length of the $k-th (in document order) div in the XML document that has a class attribute with value 'contest'.
