syntax error, unexpected variable “$%s”, expecting “)”

Description

In a function, method or closure signature, each parameter must be separated from the next one by a comma. Here, the comma between $a and $b is missing, so once PHP has parsed $a as a complete parameter, it expects either another comma or the closing parenthesis of the argument list; instead it finds another variable.

Example

<?php

function foo($a $b) {}

?>

Literal Examples

• syntax error, unexpected variable “$b”, expecting “)”

Solutions

• Add the missing comma between the two parameters.

• Remove the extra variable if it was left over from editing.
