PHP function to backup MySql Database

2007-07-31T23:43:00.000-07:00

Yesterday i try to find a PHP script to backup MySql Database, i search a lot but finds only few, here a good one script i find it, hope this help someone to, here is it...

function mysqlbackup($host,$dbname, $uid, $pwd, $output, $structure_only)
{

//this function creates a text file (or output to a HTTP connection), that when parsed through MYSQL's telnet client, will re-create the entire database

//Parameters:
// $host: usually "localhost" but depends on where the MySQL database engine is mounted
// $dbname : The MySQL database name
// $uid : the database's username (not your account's), leave blank if none is required
// $pwd : the database's password
// $output : this is the complete filespec for the output text file, or if you want the result SQL to be sent back to the browser, leave blank.
// $structure_only : set this to true if you want just the schema of the database (not the actual data) to be output.

// **************
// IMPORTANT: If you use this function, for personal or commercial use, AND you feel an overwhelming sense of gratitude that someone actually took the time and wrote it,
// immediately go to your paypal account and send me $10 with a small comment of how and how much it helped! Set the payment recipient to woodystanford@yahoo.com .
// **************

if (strval($output)!="") $fptr=fopen($output,"w"); else $fptr=false;

//connect to MySQL database
$con=mysql_connect("localhost",$uid, $pwd);
$db=mysql_select_db($dbname,$con);

//open back-up file ( or no file for browser output)

//set up database
out($fptr, "create database $dbname;\n\n");

//enumerate tables
$res=mysql_list_tables($dbname);
$nt=mysql_num_rows($res);

for ($a=0;$a<$nt;$a++)
{
$row=mysql_fetch_row($res);
$tablename=$row[0];

//start building the table creation query
$sql="create table $tablename\n(\n";

$res2=mysql_query("select * from $tablename",$con);
$nf=mysql_num_fields($res2);
$nr=mysql_num_rows($res2);

$fl="";

//parse the field info first
for ($b=0;$b<$nf;$b++)
{
$fn=mysql_field_name($res2,$b);
$ft=mysql_fieldtype($res2,$b);
$fs=mysql_field_len($res2,$b);
$ff=mysql_field_flags($res2,$b);

$sql.=" $fn ";

$is_numeric=false;

case 4: //little weakness here...there is no way (thru the PHP/MySQL interface) to tell the difference between a tinyint and a year field type
$sql.="tinyint";

break;

default: //we could get a little more optimzation here! (i.e. check for medium ints, etc.)

default: //future support for field types that are not recognized (hopefully this will work without need for future modification)
$sql.=$ft;
$is_numeric=true; //I'm assuming new field types will follow SQL numeric syntax..this is where this support will breakdown
break;
}

//VERY, VERY IMPORTANT!!! Don't forget to append the flags onto the end of the field creator

if (strpos($ff,"unsigned")!=false)
{
//timestamps are a little screwy so we test for them
if ($ft!="timestamp") $sql.=" unsigned";
}

if (strpos($ff,"zerofill")!=false)

if ($ft!="timestamp") $sql.=" zerofill";

//End of field flags

if ($b<$nf-1)
{
$sql.=",\n";
$fl.=$fn.", ";
}
else
{
$sql.="\n);\n\n";
$fl.=$fn;
}

//we need some of the info generated in this loop later in the algorythm...save what we need to arrays
$fna[$b]=$fn;
$ina[$b]=$is_numeric;

}

out($fptr,$sql);

if ($structure_only!=true)
{
//parse out the table's data and generate the SQL INSERT statements in order to replicate the data itself...
for ($c=0;$c<$nr;$c++)
{
$sql="insert into $tablename ($fl) values (";

$row=mysql_fetch_row($res2);

for ($d=0;$d<$nf;$d++)
{
$data=strval($row[$d]);

if ($ina[$d]==true)
$sql.= intval($data);
else
$sql.="\"".mysql_escape_string($data)."\"";

if ($d<($nf-1)) $sql.=", ";

}

$sql.=");\n";

out($fptr,$sql);

}

out($fptr,"\n\n");

}

mysql_free_result($res2);

}

if ($fptr!=false) fclose($fptr);
return 0;

}

function out($fptr,$s)
{
if ($fptr==false) echo("$s"); else fputs($fptr,$s);
}
?>

Copy the above function into a file called "mysqlbackup.h" and invoke it with the following script:

include("mysqlbackup.h");
mysqlbackup("localhost","yerdatabase","yerusername","yerpassword","/home/sites/site90/web/backup/sqldata.txt", true);
?>

The database's structure has been saved to "/home/sites/site90/web/backup/sqldata.txt" FTP download it at your convenience.
