Unexplained syntax error with logical OR ( || )
I'm working With NetBeans for MAC
When is a space not a space?
When it's a non-breaking space!
The intention is:
" || "207C7C20 (hex)But what is actually in the source file is almost certainly:
" || "207C7CA0 (hex)(on stack overflow it won't be but I bet it is in the source file).
With a mac the problem is (using my own keyboard layout, but I am assuming it's similar in your case):
"|" = alt + 1" " = alt + space (accidental)So typing away, with the sequence " || " it's very easy for the alt key to still be depressed when the space bar is pressed and: voilà you get unexpected "wat" syntax errors which at face value make no sense - until you realize what the problem is.
Example:
-> cat foo.php <?php$foo = "x";if (true || $foo) {}-> php -l foo.php Parse error: syntax error, unexpected '$foo' (T_VARIABLE) in foo.php on line 4Errors parsing foo.php
