variable_set($name, $value)
includes/bootstrap.inc, line 466

Description

Set a persistent variable.

Parameters

$name The name of the variable to set.

$value The value to set. This can be any PHP data type; these functions take care of serialization as necessary.

Code

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

  $serialized_value = serialize($value);
  db_query("UPDATE {variable} SET value = '%s' WHERE name = '%s'", $serialized_value, $name);
  if (!db_affected_rows()) {
    @db_query("INSERT INTO {variable} (name, value) VALUES ('%s', '%s')", $name, $serialized_value);
  }

  cache_clear_all('variables', 'cache');

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