[Editor's note: You can achieve what you're looking for by referencing $single, rather
than copying it by value in your foreach statement. See http://php.net/foreach for more details.]
Don't know if this is known or not, but it did eat some of my time and maybe it won't eat
your time now...
I tried to add something to a multidimensional array, but that didn't work at first, look at
the code below to see what I mean:
<?php
$a1 = array( "a" => 0, "b" => 1 );
$a2 = array( "aa" => 00, "bb" => 11 );
$together = array( $a1, $a2 );
foreach( $together as $single ) {
$single[ "c" ] = 3 ;
}
print_r( $together );
/* nothing changed result is:
Array
(
[0] => Array
(
[a] => 0
[b] => 1
)
[1] => Array
(
[aa] => 0
[bb] => 11
)
) */
foreach( $together as $key => $value ) {
$together[$key]["c"] = 3 ;
}
print_r( $together );
/* now it works, this prints
Array
(
[0] => Array
(
[a] => 0
[b] => 1
[c] => 3
)
[1] => Array
(
[aa] => 0
[bb] => 11
[c] => 3
)
)
*/
