PHP를 사용하여 MySQL 데이터베이스 내보내기

Question

MySQL 데이터베이스를 .sql 파일로 내보내는 데 필요한 자습서가 있습니까? 나는 쓸모없는 셸 접근을 할 수 없다. exec 나는이 URL을 발견했다 : http://davidwalsh.name/backup-mysql-database-php하지만 코드를 살펴 봤는데이 코드는 오래되었고 잘 쓰여지지 않았다. 인터넷을 살펴 봤지만 대부분의 자습서에서는 셸 액세스가 필요합니다. 나머지는 오래된 것입니다.

미리 감사드립니다.

Answer 1

phpMyAdmin이 없으면 mysql 로그인과 같은 PHP CLI 명령으로 작성하고 db 덤프를 수행 할 수 있습니다. 이 경우 shell_exec 함수를 사용합니다.

유닉스 계열의 시스템에서

Answer 2

에서, mysqldump는의 위치를 ​​표시 명령을 어느 사용이 시도 :

<?php 
$dbhost = 'localhost'; 
$dbuser = 'root'; 
$dbpass = 'password'; 
$dbname = 'test'; 
$mysqldump=exec('which mysqldump'); 


$command = "$mysqldump --opt -h $dbhost -u $dbuser -p $dbpass $dbname > $dbname.sql"; 

exec($command); 
?>

Answer 4

다음과 같은.

PHP 파일에서 데이터베이스 백업 쿼리를 실행합니다.

<?php 
$DB_HOST = "localhost"; 
$DB_USER = "xxx"; 
$DB_PASS = "xxx"; 
$DB_NAME = "xxx"; 

$con = new mysqli($DB_HOST, $DB_USER, $DB_PASS, $DB_NAME); 
if($con->connect_errno > 0) { 
    die('Connection failed [' . $db->connect_error . ']'); 
} 

$tableName = 'yourtable'; 
$backupFile = 'backup/yourtable.sql'; 
$query  = "SELECT * INTO OUTFILE '$backupFile' FROM $tableName"; 
$result = mysqli_query($con,$query); 
?> 

방금과 같은 LOAD DATA INFILE에 쿼리를 실행하는 데 필요한 백업을 복원하려면 :

<?php 
$DB_HOST = "localhost"; 
$DB_USER = "xxx"; 
$DB_PASS = "xxx"; 
$DB_NAME = "xxx"; 

$con = new mysqli($DB_HOST, $DB_USER, $DB_PASS, $DB_NAME); 
if($con->connect_errno > 0) { 
    die('Connection failed [' . $db->connect_error . ']'); 
} 

$tableName = 'yourtable'; 
$backupFile = 'yourtable.sql'; 
$query  = "LOAD DATA INFILE 'backupFile' INTO TABLE $tableName"; 
$result = mysqli_query($con,$query); 
?> 

Answer 5

이 도구가 유용 할 수 있습니다 아래 테이블 백업을 생성하는 SELECT INTO OUTFILE 쿼리를 사용하는 예입니다 그것은 순수한 PHP를 기반으로 내보내기 유틸리티입니다 : 당신은 그것을 작동하거나 나에게 100 %이 명령을 사용할 수 있습니다 https://github.com/2createStudio/shuttle-export

Answer 6

exec('C:\\wamp\\bin\\mysql\\mysql5.6.17\\bin\\mysqldump.exe -uroot DatabaseName> c:\\database_backup.sql'); 

참고 :
C:\\wamp\\bin\\mysql\\mysql5.6.17\\bin\\mysqldump.exe은 mysqldump 앱의 경로이며, PC에서 확인하십시오.

-uroot는 데이터베이스가 암호로 보호되어있는 경우 -u{UserName}

다음이 sentense -p{YourPassword}

Answer 7

에게 -uroot 후 PHP 스크립트를 사용하여 데이터베이스를 내보낼 수있는 가장 좋은 방법을 추가 할 수 있습니다.
