要求用ＰＨＰ写，按日期分类，如下：
04-20　　　[Thread-？]　出现？次
.

按楼主要求,以下代码绝对正解:
<?php
$f = file("test.txt");
$count = array();

foreach ($f as $line) {
//echo $line . "<br>\n";
eregi("date:(.+) time:.*",$line,$e);
//echo $e[0] . "<br>";
if(isset($count[$e[1]])) $count[$e[1]] += 1;
else $count[$e[1]] = 1;
//echo $e[1] . ": ". $count[$e[1]] . "<br>";
}
foreach($count as $key => $line){
echo $key . ":" . $line . "<br>";
}
?>

有点乱,整理后重发一遍:

echo $key . ":" . $line . "<br>";
}

楼主你的结果怎么是＂:16＂

我要的是　04-20　　　[Thread-？]　出现？次
04-2１　　　[Thread-？]　出现？次
　．．．．

[zysoft17]

还不完全明白你的意思. 你是想将 [Thread-？]　是的?(值)进行汇总,还是统计[Thread-？]出现的次数啊?
