Java中的for循环和PHP中的foreach循环之间的区别

Question

In PHP we use....

foreach ($array as $value) {
    echo $value;
}

In Java the same thing can be done using

for (int e : array) {
    System.out.println(e);
}

is there any difference between the above 2 code segments

Answer 1

This is very close to what both forms of java for-each iterator (numeric and Iterator) do, but PHP iterator also can provide keys and bind the iterated value by-reference, so you could modify it in place if you wanted to.
