Memcache::replace()

Memcache::replace - Replace value of the existing item

Syntax

bool Memcache::replace (string $key, mixed $var, int $flag, int $expire)

Arguments

  • key - The key that will be associated with the item.
  • var - The variable to store. Strings and integers are stored as is, other types are stored serialized.
  • flag - Use MEMCACHE_COMPRESSED to store the item compressed (uses zlib).
  • expire - Expiration time of the item. If it\'s equal to zero, the item will never expire. You can also use Unix timestamp or a number of seconds starting from current time, but in the latter case the number of seconds may not exceed 2592000 (30 days).

Description

Memcache::replace() should be used to replace value of existing item with key. In case if item with such key doesn't exists, Memcache::replace() returns FALSE. For the rest Memcache::replace() behaves similarly to Memcache::set(). Also you can use memcache_replace() function.
