Some programming languages have such a swap function built in, but PHP seems to lack such a function. So, one was created to fill the need. It only handles simple, single variables, not arrays, but it is still a very handy tool to have. Strict typing. By default, PHP will coerce values of the wrong type into the expected scalar type if possible. For example, a function that is given an integer for a parameter that expects a string will get a variable of type string. It is possible to enable strict mode on a per-file basis. In Java, I can pass an object straight in parameter public int foo (Bar bar) { call the methods from Bar class } So how can I do same thing with PHP. Thanks This is my code: class Photo.
