How can PHP documentation help in resolving common issues like string length?

When dealing with string length issues in PHP, it is important to refer to the PHP documentation to understand the functions available for manipulating strings. One common issue is determining the length of a string, which can be easily resolved using the `strlen()` function in PHP. This function returns the number of characters in a string, allowing you to accurately determine the length of the string. 

$string = "Hello, World!";
$length = strlen($string);
echo "The length of the string is: " . $length;
