php - Why does this array_walk function throw an error?

Question

array_walk ($this->something, [$this, 'function_name'], $part_something);

Parse error: syntax error, unexpected '[' in /.../...php on line 67

This works on my local test environment, but not on the server.

Answer 1

Are you running PHP 5.4 in production? If not the bracket syntax is not a valid way to represent an array in PHP 5.3 and below as it is a new feature in 5.4.

Answer 2

試してみてください：

array_walk ($this->something, array($this, 'function_name'), $part_something);
