Array: required. specifies an array: value: optional. you can specify a value, then only the keys with this value are returned: strict: optional. used with the value parameter. possible values: true - returns the keys with the specified value, depending on type: the number 5 is not the same as the string "5". false - default value.. Arrays. an array in php is actually an ordered map. a map is a type that associates values to keys.this type is optimized for several different uses; it can be treated as an array, list (vector), hash table (an implementation of a map), dictionary, collection, stack, queue, and probably more.. The big difference here is that, in the first case you are accessing the array's sub-value via the main array itself with a key to the element which is currently being pointed to by the array pointer..
Edit: if you've got the same "keys" for multiple values, i would probably create a specific type for this - it's not clear what sort of entity this is meant to represent, but you should create a class to model it, and add appropriate behaviour to it as required.. Two problems: array_push adds its 2nd+ parameters as new values (not key-value pairings as array_merge does), and php 7 happily accepts the array() array syntax (as well as the shorthand [] syntax) – chris forrence aug 15 '17 at 16:15. I have an array as the following: function example() { /* some stuff here that pushes items with dynamically created key strings into an array */ return array( // now lets pretend....
