PHP associative arrays support key-value initialization.
Associative arrays can use integer or string keys.
Their keys do not need to be ordered or contiguous.
Special initialization syntax defines both keys and values.
The double arrow (=>) denotes the mapping between a key and its value.
Example initialization: $arr = array(...).
The string key "foo" maps to the value 5.
The integer key 4 maps to the string value "bar".
The integer key 0 maps to the value 3.14.

"Since associative arrays in PHP can be indexed by either integers or strings and need not be ordered or contiguous, we can use a special key-value initialization syntax to define not only the values, but the keys that map to those values when we initialize an array. The “double arrow,” => is used to denote the mapping.\n\n1 $arr = array(\n\n2 \"foo\" => 5,\n\n3 4 => \"bar\",\n\n4 0 => 3.14,\n\n549"
