When developing web applications, using PHP to traverse and display image arrays is a common requirement. Since PHP is flexible and powerful, it can accomplish this task easily. This article will teach you how to iterate through an array of images and display them on a web page.

First, we need to create an array containing the image file names. You can use some simple PHP code to achieve this task.

$images = array("image1.jpg", "image2.jpg", "image3.jpg");

Copy after login

Next, we need to iterate through this image array and display each image on the web page. We can use PHP's foreach loop to iterate over the array. Within the loop, we need to specify the path to the image we want to display and then display it on the page using the HTML <img> tag. Here is the sample code:

foreach($images as $image) {
   echo '<img src="' . $image . '">';
}

Copy after login

In the above code, $images is the array we want to iterate through. $image is the file name of each image in the loop. The echo statement is used to output the complete HTML code of the <img> tag to the browser. The src attribute specifies the path to the image to be displayed.

If we wanted to display a title or description for each image, we could store this information in an associative array and display it next to the image as we iterate over the array. Here is the sample code:

$images = array(
   array("image1.jpg", "美丽的沙滩"),
   array("image2.jpg", "美味的食物"),
   array("image3.jpg", "迷人的风景"),
);

foreach($images as $image) {
   echo '<div>';
   echo '<img src="' . $image[0] . '">';
   echo '<p>' . $image[1] . '</p>';
   echo '</div>';
}

Copy after login

In the above code, we use a multidimensional array containing the image file name and description. In the loop, we use $image[0] to get the image file name and $image[1] to get the image description. In HTML, we use the <div> element to draw the container for each image and title, and the  element to display the title.

In short, it is very simple to traverse and display an image array using PHP, just use a simple foreach loop and the HTML img element. If you also need to display a title or description, then an associative array is a good choice. Hope this article can be helpful to you, thank you!
