* VarExporter allows serializing PHP data structures to plain PHP code (like var_export())
|
||
|
|
* while preserving all the semantics associated with serialize() (unlike var_export()).
|
||
|
|
*
|
||
|
|
* By leveraging OPcache, the generated PHP code is faster than doing the same with unserialize().
