HOW TO USE THE strlen() FUNCTION IN PHP

The strlen() function gives you a count of the number of characters in a string.

Example 1:

$string="Vacation";
$noOfChars=strlen($string);

echo $noOfChars;

The above will output: 8

Example 2:

$string="My Name Is John Smith";
$noOfChars=strlen($string);

echo $noOfChars;

The above will output: 21. Note that a single whitespace is also considered a character.
