我有一个像下面给出的大字符串，我只从第6个索引中从|和~爆炸字符串后存在的字符串中检索日期。并在组合框中显示日期。现在我将整个字符串与从组合框中选择的日期进行比较，并打印匹配的日期。这里一切都很好，但现在我想如果用户不选择任何日期意味着当第一次页面打开打印第一个日期匹配整个字符串。意味着当用户第一次访问这个页面时，他不会选择任何东西，然后打印第一个匹配所有字符串的日期。

请尽快帮助我。谢谢
我不能清楚地理解问题，但我正在回答我所理解的问题。如果这不是你想要的评论。
$causelistarray = explode('|',$return);
$causelistlen= count($causelistarray);
if(isset($_GET[ "selecteddate" ])){
$selecteddate = $_GET[ "selecteddate" ];
}else{
$selecteddate = explode ('~',$causelistarray[0])[6];//get very first date of data
for( $a=1;$a<$causelistlen; $a++){
$tmp=explode ('~',$causelistarray[$a])[6];
if($tmp<$selecteddate)
$selecteddate=$tmp;
}
}
for( $a=0;$a<$causelistlen; $a++)
