PHP - Backup Of Database Php Mysql (help Required)

I looked into this everywhere,but the code does not make sense, is not properly documented and is outdated.


Ive been trying to achieve this for the past hour.

Anybody know how I can do this?

After spending 3 days on internet and struggling with so many different forums , i have found this forum where i believe i will get the solution for my problem.

Friends, I am zero in PHP, but still i have managed to do something to fulfill my requirement.

I am stuck with one thing now..So i need help on....

I am using one html+php form to submit database into mysql.
I created a display of that table through php script on a webpage.
Now i want a datepicker option on that displayed page by which i should able to select the date range and display the data of that date range from my mysql table.
And then take a export of data displayed of selected date range in excel.

This displayed page is login protected, so i want after login the next thing comes in should show a sate selection option which should be fromdate to to date , and then records should displayed from the database and i can take export of those displayed results in excel file.
The code i am using on this page is below which do not have any thing included for excel export and datepicker script, I am pasting the code here and request you to please include the required code in it as required.

Thanks In advance

I have been searching the web and I can't fond anyone that has working code for backing up database with PHP. Most of them have the notorious depreciated ereg_replace function.

Does anyone know of a simple solution? I want it to backup all the tables in the database

I am using small script (with crone) to backup database every morning, zip and send me mail (with .sql/zip attached).


But backup is not in UTF-8 format, so I get this:
"Č" -> "C"
"Š" -> "S"
etc.


I have tried various solution but nothing works. Also tried utf_encode() function, but then I get strange characters.


Script looks like this:


function backup_tables($host,$user,$pass,$name,$tables = '*',$date)
{

$link = mysql_connect($host,$user,$pass);
mysql_select_db($name,$link);

//ALL TABLES
if($tables == '*')
{
$tables = array();
$result = mysql_query('SHOW TABLES');
while($row = mysql_fetch_row($result))
{
$tables[] = $row[0];
}
}
else
{
$tables = is_array($tables) ? $tables : explode(',',$tables);
}

//GET DATA
foreach($tables as $table)
{
$result = mysql_query('SELECT * FROM '.$table);
$num_fields = mysql_num_fields($result);

$return.= 'DROP TABLE IF EXISTS '.$table.';';
$row2 = mysql_fetch_row(mysql_query('SHOW CREATE TABLE '.$table));
$return.= "\n\n".$row2[1].";\n\n";

for ($i = 0; $i < $num_fields; $i++) 
{
while($row = mysql_fetch_row($result))
{
$return.= 'INSERT INTO '.$table.' VALUES(';
for($j=0; $j<$num_fields; $j++) 
{
$row[$j] = addslashes($row[$j]);
$row[$j] = str_replace("\n","\\n",$row[$j]);
if (isset($row[$j])) { $return.= '"'.$row[$j].'"' ; } else { $return.= '""'; }
if ($j<($num_fields-1)) { $return.= ','; }
}
$return.= ");\n";
}
}
$return.="\n\n\n";
}
//SAVE
$handle = fopen('Backup-'.$date.'.sql','w+');
fwrite($handle,$return);
fclose($handle);
}

[/size]How to save .sql file in proper UTF-8 Format?[/b][/size][/font]

How would I go about using PHP to export all the data in my SQL database to a .sql file? Also how can I then import that .sql file back into the database?

Thanks!
