如果名称存在，则保存为名称（1）名称（2），依此类推

Question

There's a mysql database that stores ids and names, when users are creating names with a form they can create existent names since unique ids are the ids such as:

d49f2c32f9107c87c7bb7b44f1c8f297 name
2fa9c810fbe082900975f827e8ed9408 name

what i want to do is saving the second "name" -> "name(1)" when inserting into database.

So far what I've got is this as the idea

lets say the name entered is 'name'

$input = 'name';

select the name we want to check from mysql database

mysql_query(SELECT * FROM  `table` WHERE  `name` =  '$input');

if the result exists, then insert as $input.'(1)'

my question is what if name exists, and name(1) also exists, then how can i add the name(2) there...

Answer 1

$i = 1;
$sourceName = $name;
while( sql "SELECT COUNT(*) FROM table WHERE name = '$name'" ) {

  $name = $sourceName.' ('.$i.')';
  $i++;
}

At this point you have the final $name (with $i counting the iteration)
