Loop through an array php
Using foreach
loop without key
foreach($array as $item) {
echo $item['filename'];
echo $item['filepath'];
// to know what's in $item
echo '<pre>'; var_dump($item);
}
Using foreach
loop with key
foreach($array as $i => $item) {
echo $item[$i]['filename'];
echo $item[$i]['filepath'];
// $array[$i] is same as $item
}
Using for
loop
for ($i = 0; $i < count($array); $i++) {
echo $array[$i]['filename'];
echo $array[$i]['filepath'];
}
var_dump
is a really useful function to get a snapshot of an array or object.
Ok, I know there is an accepted answer but… for more special cases you also could use this one:
array_map(function($n) { echo $n['filename']; echo $n['filepath'];},$array);
Or in a more un-complex way:
function printItem($n){
echo $n['filename'];
echo $n['filepath'];
}
array_map('printItem', $array);
This will allow you to manipulate the data in an easier way.
Starting simple, with no HTML:
foreach($database as $file) {
echo $file['filename'] . ' at ' . $file['filepath'];
}
And you can otherwise manipulate the fields in the foreach.
