Remove the last part of the comma in foreach in PHP?


Remove the last part of the comma in foreach in PHP?

To fix this issue How can I prevent the insertion of a comma at the end of the title3? , just use implode() - which is the equivalent to .join():
code :
echo implode(',', $_POST['titles']);
echo implode($_POST['titles']);
// $titles = explode(',', $_POST['titles']);
$titles = $_POST['titles'];
for($i=0; $i < sizeof($titles); $i++) {
    echo $titles[$i];
    if($i+1 != sizeof($titles)){echo ',';}
}

hop of those help? JSON is not a flat string, never try to build it by concatenating flat strings and hoping that it will come out all-right in the end.
JSON is a serialized data structure, treat it as such. Make a data structure and serialize it.
code :
$result = @{}
$result.data = @()

foreach ($vm in Get-VM) {
    $result.data += @{
        "{#VMNAME}" = $vm.Name;
        "{#VMSTATE}" = $vm.State;
    }
}

$result | ConvertTo-Json
@{
    "data" = Get-VM | % { 
        @{
            "{#VMNAME}" = $_.Name;
            "{#VMSTATE}" = $_.State;
        }
    }
} | ConvertTo-Json

Any of those help I have next code for WordPress loop of tags for single post: , Check if your loop is working on the last one:
code :
<?php if ($tags) : ?>
    <?php $count = count($tags); ?>
    <?php foreach($tags as $i => $tag): ?> 
        <a href="<?php echo get_tag_link($tag); ?>">
            <?php echo $tag->name; ?>
        </a>
        <?php if ($i < $count - 1) echo ", "; ?>
    <?php endforeach; ?>
<?php endif; ?>

wish of those help One way to solve this is to not echo out the commas in the foreach loop. Put the data you want to echo into an array, then use implode.
code :
$output = array();
foreach($result as $r) {
    $output[] = $r['lenght'];
}

echo implode(',', $output);

like below fixes the issue Here is a less-loopy method that uses array_splice() instead of array_chunk(). No count() calls, no incrementing counters, just one loop.
Code: (Demo)
code :
$cars=array( "Volvo","BMW","Toyota","Honda","Mercedes");
while($cars){                             // while there are still elements in the array...
    $chunk=array_splice($cars,0,2);       // extract first two elements (reducing $cars)
    if(isset($chunk[1])){$chunk[0].=',';} // add comma to 1st element if 2nd element exists
    $output[]=$chunk;                     // add extracted elements to multi-dim output
}
var_export($output);
array (
  0 => 
  array (
    0 => 'Volvo,',
    1 => 'BMW',
  ),
  1 => 
  array (
    0 => 'Toyota,',
    1 => 'Honda',
  ),
  2 => 
  array (
    0 => 'Mercedes',
  ),
)
$cars=array( "Volvo","BMW","Toyota","Honda","Mercedes");
while($cars){
    $chunk=array_splice($cars,0,2);
    echo "<ul><li>",implode(",</li><li>",$chunk),"</li></ul>";  // add comma to implode's glue string
}
<ul>
    <li>Volvo,</li><li>BMW</li>
</ul>
<ul>
    <li>Toyota,</li><li>Honda</li>
</ul>
<ul>
    <li>Mercedes</li>
</ul>

fixed the issue. Will look into that further By placing the HTML in a simple string variable and then using rtrim() on the resulting string before outputting it this should remove the final , from the string
code :
<?php
$out = '';

foreach ($snippet_tags as $tag_data) {
    $tags_id = $tag_data->tag_id;
    $tagsdata = $this->Constant_model->getDataOneColumn('tags', 'id', $tags_id);
    $tag_name=$tagsdata[0]->tag_name;

    // move inside loop and amend to place in a simple string var
    $out .= '<a href="' . base_url() . 'tags/' . $tag_name . '">' . $tag_name . '</a>,';
?>

echo rtrim($out, ',');
