With the continuous development of network technology, pictures, as an important visual material, have attracted more and more attention. In order to better display pictures and allow users to view picture details more conveniently, many websites have added picture enlargement functions. This article will introduce how to use PHP and Highslide to create a simple image magnification effect.
First, we need to download the Highslide plug-in. Highslide is a JavaScript plug-in that creates pop-up images and HTML content on the page. You can download the latest version of the plug-in from the Highslide official website.
Next, we need to create a PHP file to display the image. In this file, we define an editable variable $title and the image path as a constant. The code is as follows:
<?php
$title = "示例图片";
define('IMAGE_PATH', 'images/highslide-demo.jpg');
?>
<!DOCTYPE html>
<html>
<head>
<title><?php echo $title ?></title>
</head>
<body>
<a href="<?php echo IMAGE_PATH ?>" class="highslide">
<img src="<?php echo IMAGE_PATH ?>" alt="<?php echo $title ?>" title="<?php echo $title ?>" />
</a>
<script type="text/javascript" src="highslide/highslide.js"></script>
<link rel="stylesheet" type="text/css" href="highslide/highslide.css" />
<script type="text/javascript">
hs.graphicsDir = 'highslide/graphics/';
hs.align = 'center';
hs.transitions = ['expand', 'crossfade'];
hs.outlineType = 'rounded-white';
hs.fadeInOut = true;
hs.dimmingOpacity = 0.75;
hs.addSlideshow({
slideshowGroup: 'group1',
interval: 5000,
repeat: false,
useControls: true,
fixedControls: false,
overlayOptions: {
className: 'text-controls',
position: 'bottom center',
relativeTo: 'viewport',
offsetX: 0,
offsetY: -30
},
thumbstrip: {
position: 'bottom center',
mode: 'horizontal',
relativeTo: 'viewport'
}
});
</script>
</body>
</html>In the above code, we put the image in a link and added the Highslide class css style and javascript script. When the user clicks on the picture, the Highslide plug-in will pop up an enlarged picture box where the user can view the picture details.
Now, let’s run this PHP file. We will see the image displayed on the page and can use the Highslide plug-in to enlarge the image for viewing.
It should be noted that when using the Highslide plug-in, we need to place the Highslide style and script files in the folder. At the same time, we need to add the Highslide class name in the tag to make the image and the plug-in work together normally. If we want to customize the style and functionality of the plug-in, we can modify the plug-in's parameters in the JavaScript code block.
In summary, using PHP and the Highslide plug-in can easily create a simple image magnification effect. This is useful for websites that need to show details in images. Of course, we can also customize the style and functionality of the plug-in according to our own needs.
