SERIALIZE

Generates a storable representation of a value

SYNTAX

serialize ( mixed $value ) : string

PARAMETERS

value

The value to be serialized. serialize() handles all types, except the resource-type and some objects (see note below). You can even serialize() arrays that contain references to itself. Circular references inside the array/object you are serializing will also be stored. Any other reference will be lost. When serializing objects, PHP will attempt to call the member functions __serialize() or __sleep() prior to serialization. This is to allow the object to do any last minute clean-up, etc. prior to being serialized. Likewise, when the object is restored using unserialize() the __unserialize() or __wakeup() member function is called.

Note: Object's private members have the class name prepended to the member name; protected members have a '*' prepended to the member name. These prepended values have null bytes on either side.

RETURN

Returns a string containing a byte-stream representation of value that can be stored anywhere. Note that this is a binary string which may include null bytes, and needs to be stored and handled as such. For example, serialize() output should generally be stored in a BLOB field in a database, rather than a CHAR or TEXT field.
