PHP current() Function Explained

In PHP, the current() function is used to return the value of the element that the current pointer is pointing to in an array. It specifically returns the value of the element that the current array pointer is pointing to, without moving the pointer.

Here is a simple example to illustrate the purpose of the current() function:

$fruits = array("apple", "banana", "cherry");

// 将数组指针移动到第一个元素
echo current($fruits); // 输出: apple

// 此时数组指针仍然指向第一个元素
echo current($fruits); // 输出: apple

In this example, we first created an array named $fruits containing three types of fruits. Next, we used the current() function to retrieve the value of the element currently pointed to by the array pointer (which is the first element, “apple”). It is important to note that even though we called the current() function multiple times, the array pointer did not move and still points to the first element.

In conclusion, the current() function is used to retrieve the value of the element currently pointed to in an array.
