php analysis of generating random strings using str_shuffle() function

This article describes the method of generating a random string using the str_shuffle() function in PHP. Shared for everyone's reference, as follows:

str_shuffle(): Randomly shuffle the order of the string.

By combining the str_shuffle() function with the substr() function, you can generate a string that is different each time.

Here are two examples of the str_shuffle() function:

Example 1:Randomly generate strings of length10Bit numeric string.

$str="QWERTYUIOPASDFGHJKLZXCVBNM1234567890qwertyuiopasdfghjklzxcvbnm";
str_shuffle($str);
$name=substr(str_shuffle($str),26,10);
echo $name;

Run Result: bdgNIC04wF

Example 2:Generated a string starting with NT.10Bit String.

$str="QWERTYUIOPASDFGHJKLZXCVBNM1234567890qwertyuiopasdfghjklzxcvbnm";
$str='NT'.substr(str_shuffle($str),5,8);
echo $str;

Run Result: NTZYwKiDaF
