I specifically want to access the first element of the first and last row in a multidimensional array. I cannot seem to figure out a good way to do this.
Any help would be appreciated.
Thanks!
Jake

Code: Select all
<?php
// Numeric
$array = array
( 0 => array
( 0 => 'R'
, 1 => 'S'
, 2 => 'T'
)
, 1 => array
( 0 => 'U'
, 1 => 'V'
, 2 => 'W'
)
, 2 => array
( 0 => 'X'
, 1 => 'Y'
, 2 => 'Z'
)
);
// Works with numeric arrays
echo $array[0][0]; // R
echo $array[count($array) - 1][0]; // X
// Associative
$array = array
( 'zero' => array
( 'a' => 'R'
, 'b' => 'S'
, 'c' => 'T'
)
, 'one' => array
( 'a' => 'U'
, 'b' => 'V'
, 'c' => 'W'
)
, 'two' => array
( 'a' => 'X'
, 'b' => 'Y'
, 'c' => 'Z'
)
);
// Works with numeric and associative arrays
$first = reset($array);
echo reset($first); // R
$last = end($array);
echo reset($last); // X
