I am trying to echo out the results from the array in a foreach for location however running into problems with the array.

<select name="locale">
<?php
foreach ($locales at $location => $lo) {
    echo '<option value="' . $lo[0] . '">' . $lo[1] . '</option>';
}
?>
</select>

I am trying to get the location code in to the value and the easy to read location in the displayed option. Just not having much luck.

Many Thanks :-)

$lo[0] does not hold the locale. That's being stored in $lo and the location is already in $location by the definition of the foreach loop.

<select name="locale">
<?php
foreach ($locales at $lo => $location) {
    echo '<option value="' . $lo . '">' . $location . '</option>';
}
?>
</select>

$lo is not an array, it's a string like 'Afar (Djibouti)'. $lo[0] is the first character, $lo[1] is the second character.

You want to use $location and $lo in your options. When you write foreach ($locales as $location => $lo), the array keys go in $location, and the corresponding values go in $lo.

Also you have a typo: at should be as.

foreach ($locales as $location => $lo) {
    echo '<option value="' . $location . '">' . $lo . '</option>';
}
