如何检查它是否是foreach循环中的最后一个元素

Question

I have a foreach loop which get's the jobs name. Next to each job I have a button "Complete". When user click complete, it hides the job from page. User can do jobs in any order so he might click first, than last.

Once all the jobs are completed, I want user to automatically go to the next tab.

My question is How i can check if this was the last job in foreach loop. User can hide jobs in any order; so how I can determine if it's last job than go to the next tab.

Here is loop.

foreach ($array2 as $key => $value) { ?>
    <div class="panel panel-default center-block">
        <div class="panel-body">
            <div class=row>
                <div class="col-md-4">
                    <h2 style="color:orangered" class="text-center">SIP</h2>
                    <img alt="" class="center-block"style="width:20%;"src="../../css/collecting/logo.png">
                    <h2 class="text-center"><?php echo $value['name_dvp']; ?></h2>
                    <h3 class="text-center">(<?php echo $value['region_dvp']; ?>)</h3>
                    <h3 class="text-center">D<?php echo $value['id_dvp']; ?></h3>
                    <h2 style="color:orangered" class="text-center"><?php echo $value['maintenancelocation_dvp']; ?></h2>
                </div>


                <div class="col-md-2">
                    <img alt="" class=" center-block developerlocationselection" style="width:35%; margin-top:10%;" src="../../css/collecting/route-select.png">

                </div>
            </div>
        </div>
    </div>
    <?php

}

Javascript

<script>
  $(document).ready(function () {
    $(".developerlocationselection").click( function () {
        alert(2);
    });
  });
</script>

Answer 1

Try this :

foreach($array as $key => $value) {

    if ($value === end($array)){
        echo 'Last';
    }

}

Answer 2

I think that the better option would be to follow what @musefan said. Otherwise you could try something like this:

$array_length = count($array2);
$current_index = 0;

foreach ($array2 as $key => $value) {

   $current_index++;

   if(current_index == $array_length){
      echo 'I found the last job!';
   }

   //Do your stuff
}
