<?php $mystr = "This is my first string."; echo strlen($mystr); ?> |
Output
The above example contains a single string that is stored in a string variable $mystr. After that, you can use the PHP strlen() and pass the string variable as an argument. The example prints the size using the PHP echo statement to get the output.
Get String Size With More than one Space
If the string contains extra spaces within the words, the PHP strlen() consider all the spaces to get the exact string length.
The below example contains the 5 spaces between the string words and there are 12 characters in the string.
