我使用一个小脚本来自动化服务器之间的模式传输,但现在我需要修改它以包含数据。我对PHP不太好,所以我请求你的帮助。 这是我到目前为止(我从其他来源得到的部分,而不是我的):
/*********** GRAB OLD SCHEMA ***********/
$db1 = mysql_connect($DB_SRC_HOST,$DB_SRC_USER,$DB_SRC_PASS) or die(mysql_error());
mysql_select_db($DB_SRC_NAME, $db1) or die(mysql_error());
$result = mysql_query("SHOW TABLES;",$db1) or die(mysql_error());
$buf="set foreign_key_checks = 0;\n";
$constraints='';
while($row = mysql_fetch_array($result))
{
$result2 = mysql_query("SHOW CREATE TABLE ".$row[0].";",$db1) or die(mysql_error());
$res = mysql_fetch_array($result2);
if(preg_match("/[ ]*CONSTRAINT[ ]+.*\n/",$res[1],$matches))
{
$res[1] = preg_replace("/,\n[ ]*CONSTRAINT[ ]+.*\n/","\n",$res[1]);
$constraints.="ALTER TABLE ".$row[0]." ADD ".trim($matches[0]).";\n";
}
$buf.=$res[1].";\n";
}
$buf.=$constraints;
$buf.="set foreign_key_checks = 1";
/**************** CREATE NEW DB WITH OLD SCHEMA ****************/
$db2 = mysql_connect($DB_DST_HOST,$DB_DST_USER,$DB_DST_PASS) or die(mysql_error());
$sql = 'CREATE DATABASE '.$DB_DST_NAME;
if(!mysql_query($sql, $db2)) die(mysql_error());
mysql_select_db($DB_DST_NAME, $db2) or die(mysql_error());
$queries = explode(';',$buf);
foreach($queries as $query)
if(!mysql_query($query, $db2)) die(mysql_error());
$result = mysql_query("SHOW TABLES;",$db1) or die(mysql_error());
$buf="set foreign_key_checks = 0;\n";
$constraints='';
while($row = mysql_fetch_array($result))
{
$result2 = mysql_query("SHOW CREATE TABLE ".$row[0].";",$db1) or die(mysql_error());
$res = mysql_fetch_array($result2);
if(preg_match("/[ ]*CONSTRAINT[ ]+.*\n/",$res[1],$matches))
{
$res[1] = preg_replace("/,\n[ ]*CONSTRAINT[ ]+.*\n/","\n",$res[1]);
$constraints.="ALTER TABLE ".$row[0]." ADD ".trim($matches[0]).";\n";
}
$buf.=$res[1].";\n";
}
$buf.=$constraints;
$buf.="set foreign_key_checks = 1";
/**************** CREATE NEW DB WITH OLD SCHEMA ****************/
$db2 = mysql_connect($DB_DST_HOST,$DB_DST_USER,$DB_DST_PASS) or die(mysql_error());
$sql = 'CREATE DATABASE '.$DB_DST_NAME;
if(!mysql_query($sql, $db2)) die(mysql_error());
mysql_select_db($DB_DST_NAME, $db2) or die(mysql_error());
$queries = explode(';',$buf);
foreach($queries as $query)
if(!mysql_query($query, $db2)) die(mysql_error());
如何修改现有代码以包含数据?
谢谢!

如果你需要传输数据/和/架构,为什么不做一个mysqldump,只是读回整个东西?这个脚本本应该做什么呢?

经过大量的链接和教程后,我设法提出了一些简单的方法!这是代码:
$connectDST = mysql_connect($DB_DST_HOST, $DB_DST_USER, $DB_DST_PASS);
mysql_select_db($DB_DST_NAME, $connectDST);
set_time_limit(0);
$connectSRC = mysql_connect($DB_SRC_HOST, $DB_SRC_USER, $DB_SRC_PASS);
mysql_select_db($DB_SRC_NAME, $connectSRC);
$tables = mysql_query("SHOW TABLES FROM $DB_SRC_NAME");
while ($line = mysql_fetch_row($tables)) {
$tab = $line[0];
mysql_query("DROP TABLE IF EXISTS $DB_DST_NAME.$tab") or die('Couldn\'t drop table:'.mysql_error());
mysql_query("CREATE TABLE $DB_DST_NAME.$tab LIKE $DB_SRC_NAME.$tab") or die(mysql_error()) or die('Couldn\'t create table:'.mysql_error());
mysql_query("INSERT INTO $DB_DST_NAME.$tab SELECT * FROM $DB_SRC_NAME.$tab") or die('Couldn\'t insert data:'.mysql_error());
echo "Table: <b>" . $line[0] . " </b>Done<br>";
}
我试图避免exec,因为有些主机不允许它......
