While using dd() function in Laravel, if my output looks like this,
Collection {#194 ▼
#items: array:3 [▼
0 => Post {#195 ▶}
1 => Post {#196 ▶}
2 => Post {#197 ▶}
]
}
what are the meanings of the codes, such as #194, #195, etc? Are they helpful in any way?
According to VarDumper documentation - that's what dd() uses behind the hood:
#14 is the internal object handle. It allows comparing two consecutive dumps of the same object.
Depending on whether the item being dumped is an object or PHP resource, you'll see # for objects and @ for resources in there. The number you're seeing after # is the ID assigned by the VarDumper to that object. It's displayed so that you can easily identify dumps for the same object, if you dump it multiple times.
