Loop through nested arrays PHP

Question

Im trying to loop through PHP arrays decoded from a json file. I get the results but it only gives me the first results of the arrays in the the file. How can I make it loop? This is my code:

foreach ($events as $event) {
 echo $event['d']['Tree1'][0]['Tree2']['Field1'] . '<br>';
 echo $event['d']['Tree1'][0]['Tree2']['Field2'] . '<br>';
 echo $event['d']['Tree1'][0]['Tree2']['Field3'] . '<br>';
}

• RiggsFolly: Look up foreach or while or for in the php manual
• Romain B.: What's the array, what do you get as a result, what do you want?
• RiggsFolly: If you want help, you had better show us the array, or at least a representative example of it. And tell us what you want as a result.

Sounds like you're trying to loop through the values of a "multidimensional array". You're starting correctly by going through your array with a loop, but then you're stuck because each element in your loop is... another array. So, to echo out the values of the child array, you want to run a second loop inside of your loop. Essentially, if your loop hits a child array, you want to loop through that array too. If you know your array is made of child arrays only, you can do this like so:

<?php
foreach ($events as $event) {
 foreach($event as $ev) {
 echo $ev;
 }
}

If you need the keys, that adds a slight layer of complexity, but nothing you can't manage.

<?php
foreach ($events as $event) {
 foreach ($event as $k=>$v) {
 echo $k .': '. $v; 
 }
}

There are some examples in the php manual as well. You can also add in conditionals if you only need data from specific keys. Good luck!
