A variable array into separate items

Question

I'm not sure where I am going wrong with this code. I'm simply trying to output an array from a variable into it's separate items.

For example:

$current_endMaps = get_post_meta($post->ID, "_tsb_postmeta_end_maps", true);

Will give me the following output...

["http://localhost/lmn-beta/wp-content/uploads/2017/10/image1.png","http://localhost/lmn-beta/wp-content/uploads/2017/10/image2.png"]

But I am trying to output this as follows...

http://localhost/lmn-beta/wp-content/uploads/2017/10/image1.png
http://localhost/lmn-beta/wp-content/uploads/2017/10/image2.png

Here is what I have so far... but this is only outputting this

Here is the code I am using..

$current_endMaps = get_post_meta($post->ID, "_tsb_postmeta_end_maps", true);
$arrlength = count($current_endMaps);
for($x = 0; $x < $arrlength; $x++) {
    echo $current_endMaps[$x];
    echo "<br>";
}

Any help would be greatly appreciated.

Is it not working? There is a simpler way to loop an array in PHP, but this should nevertheless be working. — sidyll

Whats the easier way? I'm assuming that something in wordpress is just messing up the output. — user2284703

The [ output is suspicious. View the page source of the resultant output. Do you see additional stuff in there, like broken, non-rendered HTML? Instead of echo $current_endMaps[$x] debug with var_dump($current_endMals[$x]. — Michael Berkowski

Also, incrementing for () loops are rarely used in PHP when iterating an array. This shouldn't affect your output, but instead I'd recommend foreach($current_endMaps as $current_endMap) {...} and access inside simply as echo $current_endMap — Michael Berkowski

I don't know. Something must be wrong because I've done this many times before but the output is either the same or showing errors. — user2284703

I believe you need to supply false as the third argument to get_post_meta() to get an array

see https://developer.wordpress.org/reference/functions/get_post_meta/

$single (bool) (Optional) Whether to return a single value. Default value: false

Found out what I was doing wrong...

Just added json_decode to the initial array...

$current_endMaps = json_decode(get_post_meta( $post->ID, "_tsb_postmeta_end_maps", true ));
$arrlength = count($current_endMaps);
for($x = 0; $x < $arrlength; $x++) {
    echo "<img src='".$current_endMaps[$x]."' width='100%'>";
}

Then finished the echo output as an image. Works now.
