Question

As mentioned, how do i get the last element index , for example the position of 11 in this $a ?

$a[0][0] = 0; 
$a[0][1] = 1; 
$a[0][2] = 2; 
$a[1][0] = 3; 
$a[1][1] = 4; 
$a[1][2] = 5; 
$a[2][3] = 6; 
$a[2][4] = 7; 
$a[2][5] = 8; 
$a[3][0] = 9; 
$a[4][0] = 10; 
$a[4][1] = 11;
enter code here

i will like to receive x = 1, y = 4

Answer 1

$a=array(0=>array(),1=>array(),2=>array(),3=>array(),4=>array());
$a[0][0] = 0; 
$a[0][1] = 1; 
$a[0][2] = 2; 
$a[1][0] = 3; 
$a[1][1] = 4; 
$a[1][2] = 5; 
$a[2][3] = 6; 
$a[2][4] = 7; 
$a[2][5] = 8; 
$a[3][0] = 9; 
$a[4][0] = 10; 
$a[4][1] = 11;
end($a);
$x=key($a);
echo "x=$x ";
end($a[$x]);
echo "y=".key($a[$x]);

This will output:

x=4 y=1
