Laravel's Serialization on "Jobs" Table's Migration

[kayrhan]

While looking at the migration of the "Jobs" table, a question came to my mind. As you know, Laravel uses SerializesModels trait to serialize models and their relations when the job is processing. AFAIK, this trait uses PHP's own serialize() function. Here is where the question begins: Laravel uses LONGTEXT data type for migration.

$table->longText("payload");

but PHP recommends BLOB data type for serialize() function's output.

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.

Why is Laravel using LONGTEXT instead of BLOB?
