PHP如何執(zhí)行MySQL中的一個(gè)數(shù)據(jù)庫的備份？以下是百分網(wǎng)小編搜索整理的關(guān)于php數(shù)據(jù)庫備份腳本，供參考學(xué)習(xí)，希望對(duì)大家有所幫助!想了解更多相關(guān)信息請(qǐng)持續(xù)關(guān)注我們應(yīng)屆畢業(yè)生考試網(wǎng)!
代碼如下：
<?php
// 備份數(shù)據(jù)庫
$host = "localhost";
$user = "root"; //數(shù)據(jù)庫賬號(hào)
$password = ""; //數(shù)據(jù)庫密碼
$dbname = "mysql"; //數(shù)據(jù)庫名稱
// 這里的賬號(hào)、密碼、名稱都是從頁面?zhèn)鬟^來的
if (!mysql_connect($host, $user, $password)) // 連接mysql數(shù)據(jù)庫
{
echo '數(shù)據(jù)庫連接失敗，請(qǐng)核對(duì)后再試';
exit;
}
if (!mysql_select_db($dbname)) // 是否存在該數(shù)據(jù)庫
{
echo '不存在數(shù)據(jù)庫:' . $dbname . ',請(qǐng)核對(duì)后再試';
exit;
}
mysql_query("set names 'utf8'");
$mysql = "set charset utf8; ";
$q1 = mysql_query("show tables");
while ($t = mysql_fetch_array($q1))
{
$table = $t[0];
$q2 = mysql_query("show create table `$table`");
$sql = mysql_fetch_array($q2);
$mysql .= $sql['Create Table'] . "; ";
$q3 = mysql_query("select * from `$table`");
while ($data = mysql_fetch_assoc($q3))
{
$keys = array_keys($data);
$keys = array_map('addslashes', $keys);
$keys = join('`,`', $keys);
$keys = "`" . $keys . "`";
$vals = array_values($data);
$vals = array_map('addslashes', $vals);
$vals = join("','", $vals);
$vals = "'" . $vals . "'";
$mysql .= "insert into `$table`($keys) values($vals); ";
}
}
$filename = $dbname . date('Ymjgi') . ".sql"; //存放路徑，默認(rèn)存放到項(xiàng)目最外層
$fp = fopen($filename, 'w');
fputs($fp, $mysql);
fclose($fp);
echo "數(shù)據(jù)備份成功";
?>
