Unexpected character in input: '\' (ASCII=92) state=1

Question

My client says he is getting this error using my script:

Warning: Unexpected character in input: \'\\\' (ASCII=92) state=1 in /path/to//header.php  on line 3         


        

Answer 1

Now, I told him he has to have PHP >= 5.3.0 and he says his PHP version is 5.3.24

What could be the problem?

His PHP version is actually < 5.3.0, whether he knows that or not.

See the error occurring on many PHP versions.
