'echo'ing a value from a 2D array?

[bryceowen]

Is there any way to echo a value from a 2D array? When I try:

PHP Code:

echo "$array_2d[0][0]"; 


I get:

Array[0]

But if I pull it to a variable first then echo the variable, it displays correctly. Is there any way to directly echo the array value or does it have to be this way? It isn't a problem, but I'd like to eliminate any extra, unnecessary variables from my code.

The quotes are unneeded and increases the load time of your script:

PHP Code:

echo $array_2d[0][0];

if it's 2d you don't need to define the vertical dimension you can just do

echo $array_2d[0];

Mwnciau: I tried your suggestion and nothing displays.

hinch: I tried your suggestion and it just returns "Array".

[hinch]

<?php
$darr = array('one','two','three','four');
echo $darr[0];
?>

works just fine take the number out of your variable atm you have array_2d change it to $arraytwod and it should work fine

appears it doesn't like numbers in array var names don't ask me why i dont know

Hinch, you are talking about a 1d array not 2d.

Bryce, are you sure there is anything in 0, 0? This:

PHP Code:

<?php

$array_2d = array ( array ( '0, 0', '0, 1', '0, 2' ), '1', array ( '2, 0', '2, 1' ) );

echo $array_2d[0][0] . '<br />';
echo $array_2d[2][1];

outputs this:

0, 0
2, 1
