PHP5 __construct没有调用，没有错误

Question

All of a sudden, a script that was working fine for quite some time has stopped, with no error. I've pinned it down to the __contruct method but cannot understand why it's happening. Simplified version of the code....

<?php
class ex1 {
    protected $dbh;
    function __construct(){
        $this->dbh = new PDO('mysql:host=localhost;dbname=db', 'user', 'pw', array(PDO::ATTR_ERRMODE => PDO::ERRMODE_WARNING));
    }
}
?>


<?php
include('ex1.class.php');
class ex2 extends ex1 {
    somefunc(){
        is_object($this->dbh); // = FALSE
    }
}
?>

The PDO constructor works on its own, in fact nothing I put in the ex1 constructor seems to run and no errors in the logs (set to E_ALL & E_STRICT).

Any ideas?

Answer 1

If, your ex2 class has a constructor on it's own, you should call the parent one from it:

class ex2 extends ex1 {

    function __contruct() {
        /* ex2::__construct() code here */
        parent::__construct();
    }

    function somefunc() {
        is_object($this->dbh);
    }
}

Also you have a typo:

somefunc() {}

should be:

function somefunc() {}
