Have you checked all the PHP methods? I have made a rough statistics on 5025 PHP reference methods. If you are a beginner in this web programming language, I will introduce several very practical PHP methods, hoping to help you!

Function1: array_rand

First, we will introduce this simple method array_rand.

Do you want to randomly retrieve one from an array? You can use rand or mt_rand to get a random number. Pass 0 and the last index value as the minimum and maximum parameters of the array, this will give you a random key that you can use to obtain the value of the array.

Of course, there is a more convenient way to implement the above function: array_rand, you only need to pass an array, it will automatically return a random key to you. As follows:

$sites = ["gbin1.com", "gbtags.com", "baidu.com", "google.com"];  $k = array_rand($sites);  $sites[$k];  

If you need more than one random value, you can also pass the second parameter to set the number of returned values so that you can get a random array.

Function2: strip_tags
