Explain rand() function in PHP

Hello guys, I am Pritvik Sharma. In this post, I am going to tell you what rand() function does in case of PHP. 
rand() function is inbuilt function in PHP which is used to generate a random integer. If you write rand() without its minimum and maximum value it will generate a random number from all possible integers. But if you want to generate a random number from given range, write this function with its minimum and maximum range.
For example
<?php 
echo rand();
 ?>
output of this program can be any integer number. like 65, 88, 2323 etc.
Use rand() function with minimum and maximum range
If you want to generate a random integer from the range given. See the below example
<?php
echo rand(100, 1000);  //this function will generate a random integer between 100 and 1000.
?>
Output of this function will be some what like 666, 123, 987 etc. 
Hope you got this function. You can learn and practice PHP mcqs here.
