How to loop through the values ​​of an array in php

In PHP, you can use a loop structure to traverse an array and output the values ​​in the array. In PHP, commonly used loop structures include for, foreach, while, etc.

The following will introduce how to use the foreach loop to output the values ​​​​in the array.

First, we need to define an array. You can use the following code to define an array containing multiple elements:

$fruits = array("苹果", "香蕉", "橙子", "梨子");

After defining the array, we can use the foreach loop to traverse the array. The foreach loop can output the values ​​in the array one by one without using subscripts.

The following is an example of using a foreach loop to output the values ​​in an array:

foreach($fruits as $fruit){
    echo $fruit . "<br>";
}

In the above example, the $fruits array is traversed using a foreach loop. $fruits represents the array name, and $fruit represents the value obtained in each loop. Each time in the loop, the value in the $fruits array is assigned to the $fruit variable, and then the value in $fruit is output.

The output result is as follows:

苹果
香蕉
橙子
梨子

As you can see, by using the foreach loop, we can easily output the values ​​in the array without using subscripts to access the array elements. This method of code is concise, easy to implement, and easy to understand.

In addition to the foreach loop, you can also use other loop structures to traverse arrays, such as for loops, while loops, etc. These loop structures can also perform similar functions, but the syntax will be slightly different.

In short, in PHP, it is a very common scenario to use a loop structure to traverse an array. By choosing an appropriate loop structure, we can easily traverse the array, obtain the values, and implement the logic of the code.
