I get this PHP error:
Parse error: syntax error, unexpected T_VARIABLE
From this line:
$list[$i][$docinfo[\'at         
        
It could be some other line as well. PHP is not always that exact.
Probably you are just missing a semicolon on previous line.
How to reproduce this error, put this in a file called a.php:
Run it:
eric@dev ~ $ php a.php
PHP Parse error:  syntax error, unexpected T_VARIABLE in
/home/el/code/a.php on line 3
Explanation:
The PHP parser converts your program to a series of tokens.  A T_VARIABLE is a Token of type VARIABLE.  When the parser processes tokens, it tries to make sense of them, and throws errors if it receives a variable where none is allowed.
In the simple case above with variable $b, the parser tried to process this:
$a = 5 $b = 7;
The PHP parser looks at the $b after the 5 and says "that is unexpected".
