What are some best practices for efficiently replacing multiple text patterns with images in a PHP script?

When replacing multiple text patterns with images in a PHP script, it is best to use an associative array to map the text patterns to their corresponding image URLs. This allows for efficient replacement of multiple patterns without the need for repetitive code. By looping through the array and using str_replace(), we can easily replace all occurrences of the text patterns with their respective images. 

// Define an associative array mapping text patterns to image URLs
$patterns_to_images = array(
    'pattern1' => 'image1.jpg',
    'pattern2' => 'image2.jpg',
    'pattern3' => 'image3.jpg'
);

// Loop through the array and replace text patterns with images
foreach ($patterns_to_images as $pattern => $image) {
    $text = str_replace($pattern, '<img src="' . $image . '">', $text);
}
