Iterates over the root edges in the heap graph

namespace HH;

function heapgraph_foreach_root(
  resource $heapgraph,
  mixed $callback,
): void;

Calls back on every root edge. The "from" field of each root edge will be root node. root nodes are also enumerable by calling heapgraph_foreach_root_node().


  • resource $heapgraph - The resource obtained with heapgraph_create
  • mixed $callback - function(darray<string, mixed> $edge): void {} See documentation for heapgraph_edge() about the "edge" array passed to $callback
