Question

<?php
class Functions {
    public static function extendSql($dbhost, $dbuser, $dbpass, $dbname) {
        // making the mysql connection dynamically editable
        $mysql_connect  =   mysql_connect($dbhost, $dbuser, $dbpass)or die("Could not connect: " . mysql_error());
        $mysql_select_db =  mysql_select_db($dbname) or die(mysql_error());
    }
    public static function whileLoop($dbuser, $dbpass, $dbname, $sql, $passedData) {
        $this->extendSql($dbuser, $dbpass, $dbname);
        $results = mysql_query($sql);       
        while ($row = mysql_fetch_array($results)) {
        echo $passedData;
        }
    }
}

Functions::whileLoop("root", "", "rand", "SELECT * FROM products",
$hello = "hi all");
?>

I get the following error when I execute the above code.

Fatal error: Using $this when not in object context in
C:\Workspace\htdocs\Misc-2\nurbell1\core\conf\misc.php on line 13

What am I doing wrong? Obviously, $this is referenced inside the classed context in my code.

Answer 1

You are using $this in a static function, which doesn´t belong to the current instance/context, and thus is unable to use $this.
