Replace last element string after looking the string in php

Question

How do I replace the last string after i have loop on each string? I was able to do this but still not complete

// here my get string ?dir=hello1/hello2/hello3

if (isset($_GET['dir'])) {
    $hrefTabs = $_GET['dir']; 
    if (!empty($hrefTabs)) {
        $arrayOfhref = explode('/', $hrefTabs);//I explode string /

        foreach ($arrayOfhref as $roothrefline) {
            $trimstrhref = preg_replace('/\s+/', '', $roothrefline); // Here i trim white space

            $mmhref = '<a href="'.$trimstrhref.'">'.$roothrefline.'</a> / '; // Here i assign each strin hyper reference

            $toreplace = $roothrefline . ' / ';
            $lastobj = substr_replace($mmhref, $toreplace, strlen($mmhref)); // here i want the last element not to have hyper reference attribut

            echo $lastobj; // but i get this at output 
            //<a href="">hello1</a> / hello1 / <a href="">hello2</a> / hello2 /<a href="">hello3</a> / hello3
        }
    }
}

My out put look like this

<a href="">hello1</a> / hello1 / <a href="">hello2</a> / hello2 /<a
href="">hello3</a> / hello3

I want to have it look like this

<a href="">hello1</a> / <a href="">hello2</a> / hello3

Before your foreach do

$lastElement = array_pop($arrayOfHref);

and display $lastElement just after your loop.

@StuartBrian Hey, it's your code, just try to implement it, if you'll succeed, you can always edit your question. The goal of stackoverflow is not to code for someone, but to help one diagnose a problem and find solution. Check if your array is declared before you call array_pop, because it seems that it's not

$arrayOfhref and $arrayOfHref are different vars. Please learn php more carefully.

$dir = "hello1/hello2/hello3";

  if(isset($dir)){
     $hrefTabs = $dir;
     if(!empty($hrefTabs)){
    $arrayOfhref = explode('/', $hrefTabs);//I explode string /
    $i = 0;
    foreach($arrayOfhref as $roothrefline) {
      $trimstrhref = preg_replace('/\s+/', '', $roothrefline); // Here i trim white space
      $mmhref = '<a href="'.$trimstrhref.'">'.$roothrefline.'</a> / '; // Here i assign each strin hyper reference
      $toreplace = $roothrefline . ' / ';

      if(++$i === count($arrayOfhref)){
        echo $roothrefline;
      } else {
        echo $mmhref;
      }
    }
  }

}

Something like this...
