Implode() array and make new line after two elements - php

Question

I am looking to echo comma separated elements of an array e.g:
Element1, Element2, Element3, Element4, Element5, Element6
However, for the purposes of keeping the echoed elements neat, I might need to go to a new line after the each second element of each line e.g
Element1, Element2,
Element3, Element4,
Element5, Element6
As is I am doing:
<?php
$labels = Requisitions::getLabelNames($id);
foreach($labels as $label) {
$labels_array[] = $label['name'];
}
echo implode(' ,', $labels_array);
?>
And obviously getting:
Element1, Element2, Element3, Element4, Element5, Element6
How then do i do a newline after each second element of a line using implode() or otherwise?

Answer 1

<?php
$labels = array('Element1', 'Element2', 'Element3', 'Element4', 'Element5', 'Element6');
# Put them into pairs
$pairs_array = array_chunk($labels, 2);
# Use array_map with custom function
function joinTwoStrings($one_pair) {
return $one_pair[0] . ', ' . $one_pair[1];
}
$pairs_array = array_map('joinTwoStrings', $pairs_array);
echo implode(',' . PHP_EOL, $pairs_array);

You can use foreach to achive it, im pasting code for you which will give you your desired output
<?php
$labels = array("Element1", "Element2", "Element3", "Element4", "Element5","Element6");
$key = 1;
$lastkey = sizeof($labels);
foreach($labels as $value)
{
if($key%2)
{
if($key==$lastkey)
{
echo $value;
}
else
{
echo $value.",</br>";
}
}
else
{
if($key==$lastkey)
{
echo $value."</br>";
}
else
{
echo $value.",</br>";
}
}
$key++;
}
?>

untested, but something like this should work
$i = 1;
foreach($labels as $label) {
echo $label;
// add a comma if the label is not the last
if($i < count($labels)) {
echo ", ";
}
// $i%2 is 0 when $i is even
if($i%2==0) {
echo "<br>"; // or echo "\n";
}
$i++;
}

For the sake of fancy:
$labels_array=array("Element 1","Element 2","Element 3","Element 4","Element 5","Element 6");
echo implode(",\n",array_map(function($i){ // change to ",<br />" for HTML output
return implode(", ",$i);
},array_chunk($labels_array,2)));

<?php
$labels = Requisitions::getLabelNames($id);
foreach($labels as $label) {
$labels_array[] = $label['name'];
}
for($i=0;$i<count($labels_array);$i++)
{ echo($labels_array[$i]);
if($i % 2 != 0)
{
echo("\n");
}else{echo(",");}
}
?>

Answer 6

$i = 1;
$str = '';
foreach($labels AS $label)
{
$str += "$label, ";
if ($i % 2 == 0)
{
$str += "\n";
}
$i++;
}
//Remove last 2 chars
$str = substr($str,0,(strlen($str)-2));

Answer 7

Unless you need the array for something else, this just builds the string...
<?php
$labels = Requisitions::getLabelNames($id);
$s='';
$i=0;
$l=count($labels);
foreach($labels as $label){
$s.=$label['name'];
// Append delimeter. Makes sure every second, and the last one, will be a line break
$s.=((++$i%2)&&($l!=$i))?' ,':"\n";
}
echo $s;
?>
If you do need the array for something, create it first and modify above as needed.
