PHP基于PDO的 mysql 查询工具
单页面实现，将页面放在任意目录即可。

效果如下：
代码如下：
1 <?php 2 3 // 权限验证 4 $user_list = [ 5 'admin' => 'password', 6 ]; 7 8 $user = $_SERVER['PHP_AUTH_USER']; 9 $pass = $_SERVER['PHP_AUTH_PW']; 10 11 if (empty($user_list[$user]) || $user_list[$user] != $pass) 12 { 13 header('WWW-Authenticate: Basic realm="My Realm"'); 14 header('HTTP/1.0 401 Unauthorized'); 15 die ("Not authorized"); 16 } 17 18 // 参数 19 $row_limit = @$_GET['row_limit'] ?: 1000; // 显示行数限制 20 $str_limit = @$_GET['str_limit'] ?: 100; // 显示值长度限制 21 $db_config = [ 22 'connect' => @$_POST['db_connect'] ?: '', 23 'user' => @$_POST['db_user'] ?: '', 24 'password' => @$_POST['db_password'] ?: '', 25 ]; 26 27 $sql = @$_POST['sql'] ?: ''; 28 29 // 查询SQL 30 function runSql($db, $sql) 31 { 32 $dt_begin = round(microtime(true) * 1000); 33 34 $con = new PDO($db['connect'], $db['user'], $db['password'], [ 35 PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES `utf8`', 36 PDO::ATTR_PERSISTENT => FALSE, 37 ]); 38 39 $con -> setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); 40 $con -> setAttribute(PDO::ATTR_CASE, PDO::CASE_LOWER); 41 42 $sql = trim($sql); 43 44 $sql_type = strtoupper(explode(' ', $sql)[0]); 45 46 if (strpos($sql, 'INTO OUTFILE') !== FALSE) 47 { 48 $sql_type = 'OUTFILE'; 49 } 50 51 $cmd = $con -> prepare($sql); 52 53 $cmd -> execute(); 54 55 $return = NULL; 56 if ($sql_type == 'SELECT' || $sql_type == 'SHOW' || $sql_type == 'DESC') 57 { 58 $return = $cmd -> fetchAll(PDO::FETCH_ASSOC); 59 } 60 else if ($sql_type == 'INSERT') 61 { 62 $return = $con -> lastInsertId(); 63 } 64 else 65 { 66 $return = $cmd -> rowCount(); 67 } 68 69 $dt_begin = round(microtime(true) * 1000) - $dt_begin; 70 $res = [ 71 'use_time' => $dt_begin, 72 'data' => $return, 73 ]; 74 75 return $res; 76 } 77 78 // 执行SQL 79 $res = null; 80 $error = ''; 81 if (!empty($sql)) 82 { 83 try 84 { 85 $res = runSql($db_config, $sql); 86 } 87 catch(Exception $ex) 88 { 89 $error = $ex; 90 } 91 } 92 93 // 格式化值输出 94 function f($v) 95 { 96 global $str_limit; 97 98 $row_count = count(explode("\n", $v)); 99 100 $v = htmlspecialchars($v); 101 $v = nl2br($v); 102 103 if (strlen($v) > $str_limit) 104 { 105 $v = substr($v, 0, $str_limit) .
