Are there any best practices for efficiently counting occurrences of a string in a text using PHP?
When counting occurrences of a string in a text using PHP, one efficient approach is to use the `substr_count()` function. This function takes two parameters - the string to search for and the text to search within - and returns the number of occurrences of the string in the text. By using `substr_count()`, you can quickly and easily determine the frequency of a specific string in a given text.
$text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis nec odio.";
$searchString = "consectetur";
$count = substr_count($text, $searchString);
echo "The string '$searchString' appears $count times in the text.";
