我尝试在命令行中使用mysql dump并且它有效。我怎么在PHP中做到这一点? 我从互联网上找到了这个代码,并尝试了它。
<?php
ob_start();
$username = "root";
$password = "mypassword";
$hostname = "localhost";
$sConnString = mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");
$connection = mysql_select_db("test",$sConnString)
or die("Could not select DB");
$command ="C:\wamp\bin\mysql\mysql5.1.36\bin --add-drop-table --host=$hostname --databases test > C:\wamp\www\test\tester.sql";
我真的不明白以下代码的含义: 系统($命令);
$dump = ob_get_contents();
ob_end_clean();
$fp = fopen("dump.sql", "w");
fputs($fp, $dump);
fclose($fp);
?>
我将生成的.sql文件导入数据库,我从phpmyadmin收到此错误:
There seems to be an error in your SQL query. The MySQL server error output below, if there is any, may also help you in diagnosing the problem
ERROR: Unknown Punctuation String @ 3
STR: :\
SQL:

E:\Users\Nrew\Documents>set path=C:\wamp\bin\mysql\mysql5.1.36\bin;
E:\Users\Nrew\Documents>set path=C:\wamp\bin\mysql\mysql5.1.36\bin;
SQL query:

MySQL said:

请帮助,我想学习如何在php中执行此操作。
答案 0 :(得分:1)
system($command);
执行外部mysqldump
命令。
我真的不明白你粘贴的脚本,它看起来像两个脚本的混合?
无论如何,转储文件中的语法错误可能意味着您的版本不匹配(4.x在目标服务器上运行?)。
使用compatible
开关生成在目标版本中工作的转储文件,例如。
--compatible=mysql40
