full - Exportar base de datos MySQL usando solo PHP

php backup full mysql database

Question

¿Alguien tiene un tutorial para exportar una base de datos MySQL a un archivo .sql? No tengo acceso de shell, así que no puedo usar el código. Encontré este URL: http://davidwalsh.name/backup-mysql-database-php pero revisé el código y este código es antiguo y no es bueno. escrito. He buscado en Internet, pero para la mayoría de los tutoriales necesito acceso a shell, el resto está desactualizado.

Gracias por adelantado.

Answer 2

Aquí está mi código. Esto hará una copia de seguridad de la base de datos MySQL y la almacenará en la ruta especificada.

<?php
function backup_mysql_database($options){
$mtables = array(); $contents = "-- Database: `".$options[''db_to_backup'']."` --/n";
$mysqli = new mysqli($options[''db_host''], $options[''db_uname''], $options[''db_password''], $options[''db_to_backup'']);
if ($mysqli->connect_error) {
die(''Error : (''. $mysqli->connect_errno .'') ''. $mysqli->connect_error);
}
$results = $mysqli->query("SHOW TABLES");
while($row = $results->fetch_array()){
if (!in_array($row[0], $options[''db_exclude_tables''])){
$mtables[] = $row[0];
}
}
foreach($mtables as $table){
$contents .= "-- Table `".$table."` --/n";
$results = $mysqli->query("SHOW CREATE TABLE ".$table);
while($row = $results->fetch_array()){
$contents .= $row[1].";/n/n";
}
$results = $mysqli->query("SELECT * FROM ".$table);
$row_count = $results->num_rows;
$fields = $results->fetch_fields();
$fields_count = count($fields);
$insert_head = "INSERT INTO `".$table."` (";
for($i=0; $i < $fields_count; $i++){
$insert_head .= "`".$fields[$i]->name."`";
if($i < $fields_count-1){
$insert_head .= '', '';
}
}
$insert_head .= ")";
$insert_head .= " VALUES/n";
if($row_count>0){
$r = 0;
while($row = $results->fetch_array()){
if(($r % 400) == 0){
$contents .= $insert_head;
}
$contents .= "(";
for($i=0; $i < $fields_count; $i++){
$row_content = str_replace("/n","//n",$mysqli->real_escape_string($row[$i]));
switch($fields[$i]->type){
case 8: case 3:
$contents .= $row_content;
break;
default:
$contents .= "''". $row_content ."''";
}
if($i < $fields_count-1){
$contents .= '', '';
}
}
if(($r+1) == $row_count || ($r % 400) == 399){
$contents .= ");/n/n";
}else{
$contents .= "),/n";
}
$r++;
}
}
}
if (!is_dir ( $options[''db_backup_path''] )) {
mkdir ( $options[''db_backup_path''], 0777, true );
}
$backup_file_name = $options[''db_to_backup''] . " sql-backup- " . date( "d-m-Y--h-i-s").".sql";
$fp = fopen($options[''db_backup_path''] . ''/'' . $backup_file_name ,''w+'');
if (($result = fwrite($fp, $contents))) {
echo "Backup file created ''--$backup_file_name'' ($result)";
}
fclose($fp);
return $backup_file_name;
}
$options = array(
''db_host''=> ''localhost'', //mysql host
''db_uname'' => ''root'', //user
''db_password'' => '''', //pass
''db_to_backup'' => ''attendance'', //database name
''db_backup_path'' => ''/htdocs'', //where to backup
''db_exclude_tables'' => array() //tables to exclude
);
$backup_file_name=backup_mysql_database($options);

Answer 3

En los sistemas * nix, use el comando WHICH para mostrar la ubicación del mysqldump, intente esto:

<?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);
?>

Esta herramienta puede ser útil, es una utilidad de exportación pura basada en PHP: https://github.com/2createStudio/shuttle-export

Answer 5

La mejor manera de exportar la base de datos usando script php.

O agregue el quinto parámetro (matriz) de tablas específicas: array("mytable1","mytable2","mytable3") para varias tablas

<?php
//ENTER THE RELEVANT INFO BELOW
$mysqlUserName = "Your Username";
$mysqlPassword = "Your Password";
$mysqlHostName = "Your Host";
$DbName = "Your Database Name here";
$backup_name = "mybackup.sql";
$tables = "Your tables";
//or add 5th parameter(array) of specific tables: array("mytable1","mytable2","mytable3") for multiple tables
Export_Database($mysqlHostName,$mysqlUserName,$mysqlPassword,$DbName, $tables=false, $backup_name=false );
function Export_Database($host,$user,$pass,$name, $tables=false, $backup_name=false )
{
$mysqli = new mysqli($host,$user,$pass,$name);
$mysqli->select_db($name);
$mysqli->query("SET NAMES ''utf8''");
$queryTables = $mysqli->query(''SHOW TABLES'');
while($row = $queryTables->fetch_row())
{
$target_tables[] = $row[0];
}
if($tables !== false)
{
$target_tables = array_intersect( $target_tables, $tables);
}
foreach($target_tables as $table)
{
$result = $mysqli->query(''SELECT * FROM ''.$table);
$fields_amount = $result->field_count;
$rows_num=$mysqli->affected_rows;
$res = $mysqli->query(''SHOW CREATE TABLE ''.$table);
$TableMLine = $res->fetch_row();
$content = (!isset($content) ? '''' : $content) . "/n/n".$TableMLine[1].";/n/n";
for ($i = 0, $st_counter = 0; $i < $fields_amount; $i++, $st_counter=0)
{
while($row = $result->fetch_row())
{ //when started (and every after 100 command cycle):
if ($st_counter%100 == 0 || $st_counter == 0 )
{
$content .= "/nINSERT INTO ".$table." VALUES";
}
$content .= "/n(";
for($j=0; $j<$fields_amount; $j++)
{
$row[$j] = str_replace("/n","//n", addslashes($row[$j]) );
if (isset($row[$j]))
{
$content .= ''"''.$row[$j].''"'' ;
}
else
{
$content .= ''""'';
}
if ($j<($fields_amount-1))
{
$content.= '','';
}
}
$content .=")";
//every after 100 command cycle [or at last line] ....p.s. but should be inserted 1 cycle eariler
if ( (($st_counter+1)%100==0 && $st_counter!=0) || $st_counter+1==$rows_num)
{
$content .= ";";
}
else
{
$content .= ",";
}
$st_counter=$st_counter+1;
}
} $content .="/n/n/n";
}
//$backup_name = $backup_name ? $backup_name : $name."___(".date(''H-i-s'')."_".date(''d-m-Y'').")__rand".rand(1,11111111).".sql";
$backup_name = $backup_name ? $backup_name : $name.".sql";
header(''Content-Type: application/octet-stream'');
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=/"".$backup_name."/"");
echo $content; exit;
}
?>

Answer 6

Prueba lo siguiente.

Ejecute una consulta de respaldo de la base de datos desde un archivo PHP. A continuación se muestra un ejemplo del uso de la consulta SELECT INTO OUTFILE para crear una copia de seguridad de tabla:

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

Para restaurar la copia de seguridad, solo necesita ejecutar la consulta LOAD DATA INFILE de esta manera:

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

Answer 7

Puedes usar este comando o me funciona al 100%

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

Nota:
C://wamp//bin//mysql//mysql5.6.17//bin//mysqldump.exe es la ruta para la aplicación mysqldump, revisa tu pc.

-uroot es -u{UserName}

Si su base de datos está protegida con contraseña, agregue después de -uroot este sentense -p{YourPassword}

Answer 8

Si no tiene phpMyAdmin , puede escribir en los comandos de php CLI, como iniciar sesión en mysql y realizar db dump. En este caso, usaría la función shell_exec .
