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);

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 .
