PHP - Foreach 循环

Question

编辑：基本上在 2 个 foreach 中，有名为 s1en、s1enkey、s1dl、s1dlkey、s1dlvalue 的变量。我需要那些'1'来增加每个循环，但是如何？

s1en、s1enkey、s1dl、s1dlkey、s1dlvalue的PHP：

<?php

//Explode for Season 1 Downloads
if($r['s1downloads'] != '') { $s1dl = explode("~", $s1downloads); }

//Explode for Season 1 Episode Names
if($r['s1episodenames'] != '') { $s1en = explode("~", $s1episodenames); }

//Explode for Season 2 Episode Names
if($r['s2episodenames'] != '') { $s2en = explode("~", $s2episodenames); }

//Explode for Season 3 Episode Names
if($r['s3episodenames'] != '') { $s3en = explode("~", $s3episodenames); }

?>

explode() 中 ~ 之后的变量是 $r['s3episodenames'] ，它只是从数据库中获取信息。

PHP主要代码：

<?php

    $count = '1';

    for( $count=1; $count<101; $count++ ) {

        if($seasoncount = $count) {
            echo '<fieldset style="display: none;" id="season'.$count.'episodes" class="pure-group">';
            echo '<h2 style="color: #fff; display:inline-block">Episode</h2>';
            echo '<select style="display: inline-block; width: 50%;" id="selectseason'.$count.'episode" onload="javascript:season'.$count.'episodesChange()" onchange="javascript:season'.$count.'episodesChange()">';

            foreach ($s1en as $s1enkey ) {
                echo '<option>'.$s1enkey.'</option>';
            }

            echo '</select>';
            echo '<span id="s'.$count.'buttons">';

            foreach ($s1dl as $s1dlkey=>$s1dlvalue ) {
                echo '<button id="season'.$count.'episode'.($s1dlkey+1).'" type="button" onclick="window.open(\'http://crime.pw/tv/download/?url='.$s1dlvalue.'&ref='.$imdbid.'\');" class="pure-button pure-input-1-2 pure-button-primary" style="display: none;">Download Episode '.($s1dlkey+1).'</button>';
            }

            echo '</span></fieldset>';
        }

    }

?>
