We recognize the operator and the region of the mobile phone

Like walking on the Internet, I came across an interesting link - Codes of mobile operators . And I really wanted to have such a database locally.

Under the dump there is a mysql database dump, php code for its use and a script parser for updating.



First you need to download the database .

Then you can get data from the database like this:

<?php

$config[ 'mysql_host' ] = 'localhost' ;

$config[ 'mysql_user' ] = 'root' ;

$config[ 'mysql_password' ] = '' ;

$config[ 'mysql_base' ] = 'smsprice' ;



define( "PREFIX" , "mtt_" );



$mysql = new mysqli($config[ 'mysql_host' ],$config[ 'mysql_user' ],$config[ 'mysql_password' ],$config[ 'mysql_base' ]);

$mysql->query( "SET NAMES 'cp1251'" );



$number = '+7(910)89-480-23' ;



$number = preg_replace( '/[^0-9]+/' , '' ,$number);



if (strlen($number) == 11) {

$number = substr($number,1);

}



if (strlen($number) == 10) {

$def = substr($number,0,3);

$code = substr($number,3);

$stmt = $mysql->stmt_init();

$stmt->prepare(

'SELECT regions.name AS region, operators.name AS operator ' .

'FROM `' .PREFIX. 'codes` AS codes ' .

'INNER JOIN `' .PREFIX. 'regions` AS regions ON regions.id = codes.region ' .

'INNER JOIN `' .PREFIX. 'operators` AS operators ON operators.id = codes.operator ' .

'WHERE `def` = ? ' .

'AND ? < `to` ' .

'AND ? > `from`'

);

$stmt->bind_param( "iii" , $def, $code, $code);

$stmt->execute();

$stmt->bind_result($region, $ operator );

while ($stmt->fetch()) {

echo " — " .htmlspecialchars($region). "<br/>\r\n" ;

echo " — " .htmlspecialchars($ operator ). "<br/>\r\n" ;

}

$stmt->close();

} else {

echo ': ' ;

}

?>

I'm not sure about the speed of requests and the structure of the database, so if someone advises how to do it right, I will be very grateful.

If you do not want to suffer with the filling of the base and php, then you can see how it works here .



UPD:

At the request of the workers, the parser code for updating the database with mtt:

')

<?php

set_time_limit(0);
