//求更有效率的方法
<?php //1生成一个10000行文本文件,每行一个随机数字
for($i=0;$i<10000;$i++)
{
file_put_contents("1.txt",rand(0,1000)."\n",FILE_APPEND);
}
//2统计这个文件里面每个数字重复出现的次数
$a=fopen("1.txt","r");
$list=array();
$tj=array();
while($b=fgets($a))
{
    $list[]=$b;
    if(in_array($b,$list))
    {
        $tj[$b]+=1;
    }
}
//$re=array_count_values($list); //不能使用这个函数
echo "<pre class="brush:php;toolbar:false">";
var_dump($tj);
echo "
Copy after login
";


------解决方案--------------------
按你的思路,统计部分,这样更好,

PHP code

while($b=fgets($a))
{
        if(isset($list[$b]))
    {
        ++$list[$b];
    }
    else
    {
        $list[$b]    = 1;
    }
} <div class="clear">
                 
              
              
        
            </div>
Copy after login
