I found it neccesary to create a function that joins the contents of a single dimension from a 2-d
array. Here's the code in case anyone else should need to do the same:
<?php
function join_2d($glue, $pieces, $dimension = 0){
//joins the values of a single dimension in a 2-d array
$rtn = array();
foreach($piece as $key => $value){
if(isset($value[$dimension])){
$rtn[] = $value[$dimension];
}
}
return join($glue, $rtn);
}
?>
The dimension argument can be a positive integer or a named index. Here is an example:
<?php
$testarray = array(array(1 => 'a', 'three' => 1),
array(1 => 'b', 'three' => 2),
array(1 => 'c', 'three' => 3),
array(1 => 'd', 'three' => 4),
array(1 => 'e', 'three' => 5));
print "<pre>"; print_r($testarray); print "</pre>";
print join_keys(", ", $testarray, 1) . "<br>";
print join_keys(", ", $testarray, 'three') . "<br>";
?>
