Problem 1:
We want to parse each element of an array contained in an object, but
without leaving the scope of the object, and without use global vars.
Our code contain an error, and you have to find the error, and the solution.
Sample code here :

class object
{
var $lines ;
var $posFound ;

function object()
{
$lines = array( ... ) ;
...
}

function Search($val)
{
/* Line with error : */
array_walk($this->lines, 'searchInLines', $val );

/* solution : */
array_walk($this->lines, array( $this,'searchInLines'), $val );
}

function searchInLines(&line, $id, $valueToSearch)
{
if ( $line[$id] == $valueToSearch )
$this->posFound = $id ;
}
}
