PHP Remove <br> in last line with - php

Question

Currently I have this code:
<?php
echo '<meta name="robots" content="noindex">';
$arr = json_decode(file_get_contents("http://media1.clubpenguin.com/play/en/web_service/game_configs/ paper_items.json"),true);
foreach($arr as $item) {
$label = $item['label'];
$cost = $item['cost'];
$id = $item['paper_item_id'];
$member = $item['is_member'];
if ($member == "1") {
$member = "Yes";
}else{
$member = "No";
}
echo "$label = $id = $member = $cost";
echo ",<br>";
}
?>
What this code does it that it adds a tag after every line. This is the snippet that it happens in:
echo "$label = $id = $member = $cost";
echo ",<br>";
What I want is at the last line for the line echo ",<br>"; to NOT be ran. How do I do this? Please help!

Answer 1

Try this:
$result = array();
foreach($arr as $item) {
...
$result[] = "$label = $id = $member = $cost";
}
echo implode('<br />', $result);
Idea is to store all rows in array and join items with BR tag after your loop finished working.

Try this one:
<?php
$str = '';
$str .= '<meta name="robots" content="noindex">';
$arr = json_decode(file_get_contents("http://media1.clubpenguin.com/play/en/web_service/game_configs/ paper_items.json"),true);
foreach($arr as $item) {
$label = $item['label'];
$cost = $item['cost'];
$id = $item['paper_item_id'];
$member = $item['is_member'];
if ($member == "1") {
$member = "Yes";
}else{
$member = "No";
}
$str .= "$label = $id = $member = $cost";
$str .= ",<br>";
}
echo substr($str, 0, -5);
?>

Answer 3

I like ioseb's explode solution, but here's another easy way:
foreach($arr as $item) {
$first = isset($first) && print ",<br>";
// ...
echo "$label = $id = $member = $cost";
}
This prints the line break on all but the first iteration - but before the text, just make sure $first isn't set before running it.

Answer 4

I would recommend storing all your items in a string rather than echoing as you go. then you can remove whatever trailing characters you want when you're done before you echo just once at the end with a simple regex like...
echo preg_replace('/\<br\/\>$/','', $myTotalOutputString);

Answer 5

A small rewrite of your code:
<?php
echo '<meta name="robots" content="noindex">';
$arr = json_decode(file_get_contents("http://media1.clubpenguin.com/play/en/web_service/game_configs/paper_items.json"), true);
$outArray = array();
foreach($arr as $item) {
$label = $item['label'];
$cost = $item['cost'];
$id = $item['paper_item_id'];
$member = ($item['is_member'] == '1') ? "Yes" : "No";
$outArray[] = "{$label} = {$id} = {$member} = {$cost}";
}
echo implode(',<br>', $outArray);
?>

Quick one-liner using rtrim:
echo rtrim('test <br />', '<br />');
But I voted for the implode answer above.
