I guess you have an extra "=" sign in the '.$ret .= $pitem. "/".'. Wrap it with quotes, like '.$ret .'='. $pitem. "/".' . — user2655603

$path = "1/2/3/4";
$expath = explode("/", $path);

echo '<ul>';
foreach ($expath as $i => $pitem) {
    $slice = array_slice($expath, 0, $i + 1);
    $path = implode('/', $slice);
    echo '<li><a href="' . $path . '">' . $pitem . '</a></li>';
}
echo '</ul>';

$list = explode("/", "1/2/3/4");

This will create an array $list as:

echo $list[0]; // 1
echo $list[1]; // 2
echo $list[2]; // 3
echo $list[3]; // 4

This line is the problem: echo '<li><a href='.$ret .= $pitem. "/".'>'.$pitem.'</a></li>';

Should be formatted like:

echo "<li><a href='{$ret}={$pitem}/'>{$pitem}</a></li>";

or echo '<li><a href="'.$ret.'='.$pitem.'/">'.$pitem.'</a></li>';

Its because your $ret. Place that inside the loop. In your code you concatenate $pitem with $ret all older $ret values also get concat.

Try

<?php

$path = "1/2/3/4";

$expath =  explode("/",$path);


echo '<ul>';
foreach ($expath as $pitem) {
    $ret = '';

    echo '<li><a href='.$ret .= $pitem. "/".'>'.$pitem.'</a></li>';
}
echo '</ul>';

If you want = sign tobe there in the url then just change echo by following

 echo "<li><a href='$ret=$pitem/'>$pitem</a></li>";

PHP echo with double quotes will print variable value.
