Description

Set a persistent variable.

Parameters

$name The name of the variable to set.

<?php
function variable_set($name, $value) {
  global $conf;

  db_lock_table('variable');
  db_query("DELETE FROM {variable} WHERE name = '%s'", $name);
  db_query("INSERT INTO {variable} (name, value) VALUES ('%s', '%s')", $name, serialize($value));
  db_unlock_tables();

  cache_clear_all('variables', 'cache');

  $conf[$name] = $value;
}
?>
