APC Funções
Just so other users are aware, for the $ttl value (the third argument), you must supply the actual integer you want, not a multiplication problem. For example, previously I used:
echo apc_add('124563812', true, 60*45);
which would return 1 that it successfully stored the key/value, however it does not actually store the key/value. If you instead put the whole number:
echo apc_add('124563812', true, 2700);
You still receive a return value of 1 indicating that it stored successfully, but this time it actually does store properly.
apc_add
(PECL apc >= 3.0.13)
apc_add — Cache a variable in the data store
Descrição
Caches a variable in the data store, only if it's not already stored.
Nota: Unlike many other mechanisms in PHP, variables stored using apc_add() will persist between requests (until the value is removed from the cache).
Parâmetros
- key
-
Store the variable using this name. keys are cache-unique, so attempting to use apc_add() to store data with a key that already exists will not overwrite the existing data, and will instead return FALSE. (This is the only difference between apc_add() and apc_store().)
- var
-
The variable to store
- ttl
-
Time To Live; store var in the cache for ttl seconds. After the ttl has passed, the stored variable will be expunged from the cache (on the next request). If no ttl is supplied (or if the ttl is 0), the value will persist until it is removed from the cache manually, or otherwise fails to exist in the cache (clear, restart, etc.).
- values
-
Names in key, variables in value.
Valor Retornado
Retorna TRUE em caso de sucesso ou FALSE em falhas. Second syntax returns array with error keys.
Exemplos
Exemplo #1 A apc_add() example
<?php
$bar = 'BAR';
apc_add('foo', $bar);
var_dump(apc_fetch('foo'));
echo "\n";
$bar = 'NEVER GETS SET';
apc_add('foo', $bar);
var_dump(apc_fetch('foo'));
echo "\n";
?>
O exemplo acima irá imprimir:
string(3) "BAR" string(3) "BAR"
