PHP Program to find number of characters in the string using strlen() function

How to find the number of characters in the string using PHP?

In this program, we are finding the length of the string entered by the user. To do so we are using the built-in function strlen(). For this, we first have to read the string into the variable str and then we have to call the function strlen() with the variable str as the argument and assign it to the variable len. And at last print, the value of the variable len as the number of characters in the string entered.
