How to implode an array to new lines [duplicate]

Closed 10 months ago.
I have this array:
array(1) {
["comments"]=>
array(244) {
[113]=>
array(2) {
[0]=>
string(40) "2016-07-15 09:27 | From On Track to Done"
[1]=>
string(40) "2016-07-15 09:56 | From Done to On Track"
}
}
}
And I want to make into this array:
array(1) {
["comments"]=>
array(244) {
[113]=>
array(1) {
[0]=>
string(80) "2016-07-15 09:27 | From On Track to Done
2016-07-15 09:56 | From Done to On Track"
}
}
}
I need to keep the key [113] and merge the values.
I need all the comments to be in only one array.
In this example there are only two comments, but actually it is much more.
I tried with array_merge, array_value and a loop. I couldnt get it.

Answer 1

A more general algorithm would be :
<?php
// SAMPLE DATA.
$arr = array( "comments" => array( 0 => array( "2016-07-15 09:27 | From On Track to Done",
"2016-07-15 09:56 | From Done to On Track"
),
1 => array( "111 | aaa",
"222 | bbb",
"333 | ccc"
)
),
"posts" => array( 0 => array( "2016-07-13 08:00 | bla bla bla",
"2016-07-13 08:30 | more bla bla bla"
),
1 => array( "444 | xxx",
"555 | yyy",
"666 | zzz"
)
)
);
var_dump( $arr ); // ORIGINAL ARRAY.
$new = array();
foreach ( $arr as $key => $category ) // "COMMENTS", "POSTS", ...
{ for ( $i = 0; $i < count( $category ); $i++ ) // 0, 1, ...
{ $values = implode( $category[ $i ]," " ); // MERGE STRINGS.
$new[ $key ][ $i ] = array( $values );//WE CAN REMOVE "ARRAY" AND LEAVE ONLY "$VALUES".
}
}
var_dump( $new ); // NEW ARRAY.
?>
Result :
original array
array (size=2)
'comments' =>
array (size=2)
0 =>
array (size=2)
0 => string '2016-07-15 09:27 | From On Track to Done' (length=40)
1 => string '2016-07-15 09:56 | From Done to On Track' (length=40)
1 =>
array (size=3)
0 => string '111 | aaa' (length=9)
1 => string '222 | bbb' (length=9)
2 => string '333 | ccc' (length=9)
'posts' =>
array (size=2)
0 =>
array (size=2)
0 => string '2016-07-13 08:00 | bla bla bla' (length=30)
1 => string '2016-07-13 08:30 | more bla bla bla' (length=35)
1 =>
array (size=3)
0 => string '444 | xxx' (length=9)
1 => string '555 | yyy' (length=9)
2 => string '666 | zzz' (length=9)
new array
array (size=2)
'comments' =>
array (size=2)
0 =>
array (size=1)
0 => string '2016-07-15 09:27 | From On Track to Done 2016-07-15 09:56 | From Done to On Track' (length=81)
1 =>
array (size=1)
0 => string '111 | aaa 222 | bbb 333 | ccc' (length=29)
'posts' =>
array (size=2)
0 =>
array (size=1)
0 => string '2016-07-13 08:00 | bla bla bla 2016-07-13 08:30 | more bla bla bla' (length=66)
1 =>
array (size=1)
0 => string '444 | xxx 555 | yyy 666 | zzz' (length=29)

Answer 2

Try this:
$array['comments'][113] = implode(' ', $array['comments'][113]);

Answer 3

I don't know what is your array structure, but simple solution is:
$vals = implode("\n", $ar['comments'][113]);
$ar['comments'][113] = array();
$ar['comments'][113][] = $vals;
Or simpler:
$ar['comments'][113] = array(implode("\n", $ar['comments'][113]));

Answer 4

Thank you for the help! You were right. It was with implode.
The answer was this:
foreach ($goals["comments"] as $key => $value) {
$goals['comments'][$key][0] = implode($value, "\n");
}
