i keep getting the error Parse error: syntax error, unexpected '['
for some strange reason and i really cant figure out why, heres my skype.class
<?php
class SkypeResolver {
function __construct($db) {
$this->db = new DB($db);
}
function get_ip($username) {
$str = $this->skypeurl();
$str .= $username;
$output = file_get_contents($str);
return $output;
}
function skypeurl() {
return $this->db->fetch_array($this->db->query("SELECT * FROM `settings` WHERE `ident`='skype-api-url'"))['val'];
}
}
?>
ive tried removing the "[" but it then throws another error which i fix which then leads to another error and so on... anyone got any ideas ?

Answer 1

Like somebody said older PHP version. You need to do it the old way.
function skypeurl() {
$array = $this->db->fetch_array($this->db->query("SELECT * FROM `settings` WHERE `ident`='skype-api-url'"));
return $array['val'];
}

Answer 2

You have to use PHP 5.4 or higher to directly get array keys from functions.
This is a workaround working on any version:
function skypeurl() {
$res = $this->db->fetch_array($this->db->query("SELECT * FROM `settings` WHERE `ident`='skype-api-url'"));
return $res['val'];
}

Answer 3

A possible solution:
function skypeurl() {
$array = $this->db->fetch_array($this->db->query(\
"SELECT * FROM `settings` WHERE `ident`='skype-api-url'"));
return $array['val'];
}
