PHP Comma Delimiter or Explode for Foreach Loop [duplicate] - php

How to extract and access data from JSON with PHP?
(1 answer)
Closed 7 months ago.
I have a drag and drop JS plugin that saves strings as the following:
["кровать","бегемот","корм","валик","железосталь"]
I have found that I can use str_replace in an array to remove both brackets and " char. The issue that I now have is that I have a invalid argument for passing through the foreach loop as it cannot distinguish each individual word.
$bar = '["кровать","бегемот","корм","валик","железосталь"]';
$new_str = str_replace(str_split('[]"'), '', $bar);
foreach($new_str as $arr){
echo $arr;
}
So the data now outputted looks as follows (if I were to echo before the foreach loop):
кровать,бегемот,корм,валик,железосталь
Is there anyway in which I can use a comma as a delimeter to then pass this through the foreach, each word being it's own variable?
Is there an easier way to do this? Any guidance greatly appreciated!

Answer 1

Technically, you can use explode, but you should recognize that you're getting JSON, so you can simply do this:
$bar = '["кровать","бегемот","корм","валик","железосталь"]';
$new_str = json_decode($bar);
foreach($new_str as $arr){
echo $arr;
}
With no weird parsing of brackets, commas or anything else.

Answer 2

The function you need is explode(). Take a look here:
http://www.w3schools.com/php/func_string_explode.asp
Look at the following code:
$bar = '["кровать","бегемот","корм","валик","железосталь"]';
$new_str = str_replace(str_split('[]"'), '', $bar);
$exploding = explode(",", $new_str);
foreach($exploding as $token){
echo $token;
}

Answer 3

It looks like you've got a JSON string and want to convert it to an array. There are a few ways to do this. You could use explode
like this:
$bar = '["кровать","бегемот","корм","валик","железосталь"]';
$new_str = str_replace(str_split('[]"'), '', $bar);
$new_str_array = explode($new_str);
foreach($new_str_array as $arr){
echo $arr;
}
or you could use json_decode
like this:
$bar = '["кровать","бегемот","корм","валик","железосталь"]';
$new_str_array = json_decode($bar);
foreach($new_str_array as $arr){
echo $arr;
}

Answer 4

<?php
$aa = '["кровать","бегемот","корм","валик","железосталь"]';
$bb = json_decode($aa);
foreach($bb as $b)
echo $b."\n";
?>
and the results is,
кровать
бегемот
корм
валик
железосталь
