PHP echo values of all sub keys

In the following array:

"options": "front-electric": "pt": "Vidros Eléctricos dianteiros", "en": "Front electric" , "electric-diant-back": "pt": "Vidros Eléctricos diant. + trase.", "en": "Electric diant. + Back." , "darkened": "pt": "Vidros Escurecidos", "en": "Darkened" , "soundproofing-and-athermic": "pt": "Vidros Insonorizantes e Atérmicos", "en": "Soundproofing and Athermic"

How can i echo the value 'pt' of all sub keys from 'options' array?

I could try something similar to ['options']['pt'], but i don't understand how to refer to "front-electric", "electric-diant-back"... that are sub key from 'options' and all of them have different text.

foreach($array['options'] as $key => $obj) echo "$key: $obj['pt']"; - $key will be "front-electric", "electric...",... - $obj is the object inside "front-electric" - $obj['pt'] the value you want!

foreach($array['options'] as $key => $obj) echo "$key: $obj['pt']";

$obj

$obj['pt']

by the way the PHP array, this is in JSON format which is used by Javascript

All the answers were great, but in the end the foreach loop was the one tto go. Apologies for the delayy and many thanks to all.

This is looking more like a json string to me. If so, you will have to first, json_decode and then loop through the outputted array.

json

foreach($array['options'] as $key => $value) echo $value['pt']."<br>";

Suppose you have this from json_decode():

json_decode()

$options = [ "front-electric" => [ "pt" => "Vidros Eléctricos dianteiros", "en" => "Front electric" ], "electric-diant-back" => [ "pt" => "Vidros Eléctricos diant. + trase.", "en" => "Electric diant. + Back." ], "darkened" => [ "pt" => "Vidros Escurecidos", "en" => "Darkened" ], "soundproofing-and-athermic" => [ "pt" => "Vidros Insonorizantes e Atérmicos", "en" => "Soundproofing and Athermic" ] ];

Then simply doing : $output = array_column($options, 'pt'); will give you the needed array.

$output = array_column($options, 'pt');

Check this fiddle for your use case : https://repl.it/repls/DefinitiveWavyProblem

Their JSON is another level deeper than that though.

That makes it array_column($json['options'], 'pt'); I guess, the idea is to simply use array_column and avoid looping.

array_column($json['options'], 'pt');

array_column

Yup, definitely a good approach, just thought it was worth mentioning.

Better to use one of the built-in functions, rather than a loop. Cleaner and shorter code, possibly more efficient.

array_walk($data, function($v, $k) echo "$v[pt]n";);

You can use a foreach loop (as @Jeff mentions)

foreach

foreach($array['options'] as $key => $val) echo $val['pt'];

Try this

$json = '"options": "front-electric": "pt": "Vidros Eléctricos dianteiros", "en": "Front electric" , "electric-diant-back": "pt": "Vidros Eléctricos diant. + trase.", "en": "Electric diant. + Back." , "darkened": "pt": "Vidros Escurecidos", "en": "Darkened" , "soundproofing-and-athermic": "pt": "Vidros Insonorizantes e Atérmicos", "en": "Soundproofing and Athermic" '; $json_array = json_decode($json,true); foreach($json_array as $key=>$values) foreach($values as $subkeys=>$subvalues) print $subvalues['pt'] . "<br/>";

output

Vidros Eléctricos dianteiros

Vidros Eléctricos diant. + trase.

Vidros Escurecidos

Vidros Insonorizantes e Atérmicos
