 一个简单的日志查看方法

<?php
$handle = @fopen("log.txt", "r");
if ($handle) 
{
    $i = 1;
    while (($buffer = fgets($handle)) !== false) 
    {
        $str = '$data='.$buffer.';';
        eval($str);
        $data['get'] = urldecode($data['get']);
        $data['post'] = urldecode($data['post']);
        $data['session'] = urldecode($data['session']);
        $data['HTTP_REFERER'] = urldecode($data['HTTP_REFERER']);
        $data['HTTP_COOKIE'] = urldecode($data['HTTP_COOKIE']);
        $data['REDIRECT_URL'] = urldecode( $data['REDIRECT_URL']);
        $data['REQUEST_URI'] = urldecode($data['REQUEST_URI']);
        echo $i,',',$data['REQUEST_URI'], PHP_EOL;
        $i++;
    }
    
    if (!feof($handle)) {
        echo "Error: unexpected fgets() fail\n";
    }
    fclose($handle);
}
