Parse error in PHP - unexpected T_variable at line x. What is this error?

This is a syntax error, meaning that there is something in your code stopping it from being parsed correctly and therefore run.

What you should do is check carefully at the lines around where the error is for any simple mistakes - for instance forgetting to include semi-colons at the end of statements, or not using " correctly or ' correctly in your statements.

They can be quite fiddly to find, but by carefully checking the code around the line generating the area, you should be able to find the mistake you have made with your syntax and resolve the T_variable error.
