[php]How to convert array values to one array value with comma? - php

Question

Is it possible to connect the key genres, country, in one value
eg [genres] => value1, value2, value3
because there is a problem such that the Values from previous loop are added to the next loop

1./////////////////////////////////////////////////////////////////////
stdClass Object
(
[title] => Marsjanin
[origTitle] => The Martian
[genres] => Array
(
[0] => Array
(
[key] => 28
[value] => akcja
)
[1] => Array
(
[key] => 33
[value] => sci-fi
)
)
[country] => Array
(
[0] => Array
(
[key] => 53
[value] => USA
)
[1] => Array
(
[key] => 53
[value] => Australia
)
)
)
2./////////////////////////////////////////////////////////////////////
stdClass Object
(
[title] => Pięćdziesiąt twarzy Greya
[origTitle] => Fifty Shades of Grey
[genres] => Array
(
[0] => Array
(
[key] => 16
[value] => melodramat
)
[1] => Array
(
[key] => 33
[value] => sci-fi
)
)
[country] => Array
(
[0] => Array
(
[key] => 53
[value] => USA
)
)
)
This is my code:
foreach( $urll as $urle){
$results = My_Parser::getMovie($urle);
foreach($results as $itemz => $valuez) {
if($itemz=='genres'){
foreach($valuez as $val) {
$genr[] = $val['value'];
}}
}
$genre = implode(', ', $genr);
echo '<tr><th>'.$genre.'</th><th>Importuj</th></tr>';
}
Values from previous loop are added to the next
ex.
A
B
C
D
Result:
A = A
A+B = B
A+B+C = C
A+B+C+D = D
Output [genres]
Array
(
[0] => akcja
[1] => sci-fi
)
Array
(
[0] => akcja / Incorect value added from first array
[1] => sci-fi / Incorect value added from first array
[2] => melodramat
[3] => sci-fi
)

Answer 1

Your $genr is being appended to constantly. Reset it before entering the nested loop:
foreach( $urll as $urle){
...
$genr = array(); // Add this!
foreach($results as $itemz => $valuez) {
...
}
...
$genre = implode(', ', $genr); // Now you're good.
...
}

Answer 2

You need to initialize the array before the foreach of foreach($valuez as $val)
foreach( $urll as $urle){
$results = My_Parser::getMovie($urle);
foreach($results as $itemz => $valuez) {
if($itemz=='genres'){
$genr=array(); //initialization
foreach($valuez as $val) {
$genr[] = $val['value'];
}
$genre = implode(', ', $genr); // use the variable -- As per as your requirement.
echo '<tr><th>'.$genre.'</th><th>Importuj</th></tr>';
}
}
}
