我想从我的数据库的一个表中读取数据（从页面中选择SELECT），并根据INSERT将它们复制到多个表中。当我复制到一个或另一个表时，我的脚本工作正常，但是当我像下面那样运行它时，它只会将数据复制到第一个表中。你能帮帮我吗？
<?php
// Pripojenie na databazu s overenim pripojenia
$con = mysql_connect('localhost:8501' , 'root', '');
if(!$con) {
die("Nepripojene ".mysql_error());
}
// Vyber databazy ikarus2 s overenim vyberu
$db = mysql_select_db('ikarus2',$con);
if(!$db) {
die('Ziadny pristup k db ikarus2!'.mysql_error());
}
// MySQL SELECT from pages

在执行第二个while循环之前，请尝试使用mysql_data_seek()：
mysql_data_seek($result, 0);
记录集$result中的指针需要重置为零，否则它仍会指示它在最后。
或
首先将所有记录存储在一个数组中，然后执行foreach将数据插入数据库

我认为多个while循环会导致问题。试一试
while ($row = mysql_fetch_array($result)){
$insertoverlay = "INSERT INTO pages_language_overlay( pid, t3ver_oid, t3ver_id, t3ver_wsid, t3ver_label, t3ver_state, t3ver_stage,
t3ver_count, t3ver_tstamp, t3_origuid, tstamp, crdate, cruser_id, sys_language_uid, title, hidden, starttime, endtime,
deleted, subtitle, nav_title, media, keywords, description, abstract, author, author_email, tx_impexp_origuid, tx_realurl_pathsegment,
doktype, url, urltype, shortcut, shortcut_mode)

mysql_query($insertoverlay,$con);
$insertcontent = "INSERT INTO tt_content( pid, t3ver_oid, t3ver_id, t3ver_wsid, t3ver_label, t3ver_state, t3ver_stage, t3ver_count,

1.- 不要使用mysql_ *函数，不推荐使用，使用PDO或mysqli_ *函数
2.-我认为你不太了解mysql_fetch_array，这个函数返回下一行数据并将指针移动到下一个记录，因此，在第二个while循环mysql_fetch_array将返回false
因此，您需要在while / loop中执行两个insert语句：
// MySQL INSERT into pages_language_overlay
while ($row = mysql_fetch_array($result)){
$insertoverlay = "INSERT INTO pages_language_overlay( pid, t3ver_oid, t3ver_id, t3ver_wsid, t3ver_label, t3ver_state, t3ver_stage,
t3ver_count, t3ver_tstamp, t3_origuid, tstamp, crdate, cruser_id, sys_language_uid, title, hidden, starttime, endtime,
deleted, subtitle, nav_title, media, keywords, description, abstract, author, author_email, tx_impexp_origuid, tx_realurl_pathsegment,
doktype, url, urltype, shortcut, shortcut_mode)
VALUES ('$row[0]','$row[1]','$row[2]','$row[3]','$row[4]','$row[5]','$row[6]','$row[7]','$row[8]',
'$row[9]','$row[10]','$row[11]','$row[12]','5', '$row[13]','$row[14]','$row[15]','$row[16]','$row[17]','$row[18]',
'$row[19]','$row[20]','$row[21]','$row[22]','$row[23]','$row[24]','$row[25]','$row[26]','$row[27]','$row[28]',
'$row[29]','$row[30]','$row[31]','$row[32]')";
mysql_query($insertoverlay,$con);
$insertcontent = "INSERT INTO tt_content( pid, t3ver_oid, t3ver_id, t3ver_wsid, t3ver_label, t3ver_state, t3ver_stage, t3ver_count,
t3ver_tstamp, t3ver_move_id, t3_origuid, tstamp, crdate, cruser_id, hidden, sorting, media, layout,
deleted, starttime, endtime, fe_group, sys_language_uid, tx_impexp_origuid)
VALUES ('$row[0]','$row[1]','$row[2]','$row[3]','$row [4]','$row[5]','$row[6]','$row[7]','$row[8]',
'$row[33]','$row[9]','$row[10]','$row[11]','$row[12]','$row[14]','$row[34]','$row[20]','$row[35]','$row[17]',

该计划结构不合理。当控件进入第二个循环时，结果集已经完全消耗。相反，将它们放在同一个循环中以解决您遇到的直接问题：
// MySQL INSERT into pages_language_overlay
while ($row = mysql_fetch_array($result)){
$insertoverlay = "INSERT INTO pages_language_overlay( pid, t3ver_oid, t3ver_id, t3ver_wsid, t3ver_label, t3ver_state, t3ver_stage,
t3ver_count, t3ver_tstamp, t3_origuid, tstamp, crdate, cruser_id, sys_language_uid, title, hidden, starttime, endtime,
deleted, subtitle, nav_title, media, keywords, description, abstract, author, author_email, tx_impexp_origuid, tx_realurl_pathsegment,
doktype, url, urltype, shortcut, shortcut_mode)
VALUES ('$row[0]','$row[1]','$row[2]','$row[3]','$row[4]','$row[5]','$row[6]','$row[7]','$row[8]',
'$row[9]','$row[10]','$row[11]','$row[12]','5', '$row[13]','$row[14]','$row[15]','$row[16]','$row[17]','$row[18]',
'$row[19]','$row[20]','$row[21]','$row[22]','$row[23]','$row[24]','$row[25]','$row[26]','$row[27]','$row[28]',
'$row[29]','$row[30]','$row[31]','$row[32]')";
mysql_query($insertoverlay,$con);
$insertcontent = "INSERT INTO tt_content( pid, t3ver_oid, t3ver_id, t3ver_wsid, t3ver_label, t3ver_state, t3ver_stage, t3ver_count,
t3ver_tstamp, t3ver_move_id, t3_origuid, tstamp, crdate, cruser_id, hidden, sorting, media, layout,
deleted, starttime, endtime, fe_group, sys_language_uid, tx_impexp_origuid)
VALUES ('$row[0]','$row[1]','$row[2]','$row[3]','$row [4]','$row[5]','$row[6]','$row[7]','$row[8]',
'$row[33]','$row[9]','$row[10]','$row[11]','$row[12]','$row[14]','$row[34]','$row[20]','$row[35]','$row[17]',
'$row[15]','$row[16]','$row [36]','5','$row[26]')";
mysql_query($insertcontent,$con);
}
?>
INSERT INTO destTable (col1, col2, col3)
SELECT srcCol1, srcCol2, srcCol3 FROM srcTable;
这种方式甚至可能更快：数据不需要传送到运行PHP代码的服务器，而是返回到数据库 - 它完全由数据库处理。
