应用场景:excel一列内容比如身份证号，可能有重复的，
则用此工具快速查询那些重复及显示去重后内容。
使用：粘贴一列数据，然后提交发送。
<?php
$tm = "单列查重去重(粘贴Excel中1列内容查重)!";function tipx($str){
$str = str_replace(array("\r\n","\r","\n"),"|",Trim($str));
$strs= explode("|",$str);
$uni = array_count_values($strs);arsort($uni);
return $uni;
}function tipy($str){
$str = str_replace(array("\r\n","\r","\n"),"|",Trim($str));
$strs= explode("|",$str);
$uni = array_unique($strs);
return join("\r\n",$uni);
}function txtarea($nb,$ht="50vh") {return "<textarea style='display:inline;height:$ht;width:25vw;min-width:118px;'>$nb</textarea>";
}if($_GET["x"] == "cha"){
$tips = isset($_POST['tips']) ? $_POST['tips'] : '';
$lisa = tipx($tips); $lisar=""; $licar=tipy($tips);
foreach($lisa as $key=>$val){if($val>1) $lisar .= "$key=>$val\r\n";
}
echo txtarea("查重:重复的\r\n".$lisar);
echo txtarea("去重:删重后\r\n".$licar);
exit();
}
?>
