I am using the following PHP snippet to echo data to an HTML page. This works fine so far and returns results like the following example: value1, value2, value3, value4, value5,
How can I prevent it from also adding a comma at the end of the string while keeping the commas between the single values ?
My PHP:
<?php foreach ($files->tags->fileTag as $tag) { echo $tag . ", "; } ?>
If
$files->tags->fileTag
is an array, then you can use
$str = implode(', ', $files->tags->fileTag);
implode(", ", $files->tags->fileTag);
A simple way to do this is keep a counter and check for every record the index compared with the total item tags.
<?php
$total = count($files->tags->fileTag);
foreach ($files->tags->fileTag as $index => $tag) {
if($index != $total - 1){
echo $tag.',';
} else{
echo $tag;
}
?>
Assuming you're using an array to iterate through, how about instead of using a foreach loop, you use a regular for loop and put an if statement at the end to check if it's reached the length of the loop and echo $tag on it's own?
Pseudocode off the top of my head:
for($i = 0, $i < $files.length, $i++){
if ($i < $files.length){
echo $tag . ", ";
} else {
echo $tag;
}
}
Hope that helps x
Edit: The implode answers defo seem better than this, I'd probably go for those x
