array key help

Copy linkTweet thisAlerts:
Feb 13.2009

hi guys, try as i may i can’t seem to wrap my head around array keys.

i have an array of categories listed on no particular order.

i use asort() to get them into alphabetical order, and now
i need to loop through the array and print each one as a clickable
link with the corresponding key.

i tried using key(), with a regular ‘for loop’ but the same key is being
printed for every element of the array.

here’s my code…

asort($data); //name of array is $data

for( $i = 0; $i < sizeof($data); $i++ ){
echo “<li>$data[$i] ” . key($data);
}

how can i correct it to get the proper key?

thanks,
Michael.

@toenailsinFeb 13.2009 — you need to advance the arrays internal pointer

[CODE]for( $i = 0; $i < sizeof($data); $i++ ){
echo "<li>$data[$i] " . key($data);
next($data);
}[/CODE]

@MindzaiFeb 13.2009 — Or use foreach which was designed for this very task and is much more efficient than calling sizeof every iteration:

[code=php]
foreach ($data as $key => $value) {
echo "<li>$value $key</li>";
}
[/code]
