How can PHP be optimized to handle multiple occurrences of a search term within a text and ensure complete output?

When handling multiple occurrences of a search term within a text in PHP, you can use the `preg_replace` function with the `count` parameter set to ensure all occurrences are replaced. This function allows you to specify the maximum number of replacements to perform. By setting the `count` parameter to `-1`, you can replace all occurrences of the search term in the text. 

$text = "This is a sample text with multiple occurrences of the word 'PHP'. PHP is a popular scripting language used for web development.";
$searchTerm = "PHP";
$replacement = "JavaScript";

$replacedText = preg_replace('/' . $searchTerm . '/', $replacement, $text, -1);

echo $replacedText;
