Create an image slideshow using PHP and Highslide
With the development of Internet technology, the display effect of the website is becoming more and more important. Pictures are common elements on pages and are often used on websites to display products, services or company information. However, if it is just a simple static image display, it cannot attract the user's attention. Therefore, it is very necessary to implement dynamic display of images on the website to make users more interested in browsing.
This article will introduce how to use PHP and Highslide to create a picture slideshow. Highslide is a high-quality JavaScript image pop-up effect plug-in. It can make the display of images more beautiful, and also has various effects such as scaling, rotation, and fade-in and fade-out.
Step 1: Preparation
Before using Highslide, you need to download and decompress the Highslide compressed package. The download address is: http://highslide.com/download/. After decompression, you can get two folders: highslide and highslide-with-gallery.
The highslide folder contains the core files of Highslide, while the highslide-with-gallery folder contains image display examples and advanced features, such as gallery and thumbnail navigation.
Copy the downloaded folder to the root directory of the website.
Step 2: Write HTML code
In the web page, you need to introduce the core file of Highslide first. Add the following code in the
tag of the HTML code:<head>
<script type="text/javascript" src="highslide/highslide.js"></script>
<link rel="stylesheet" type="text/css" href="highslide/highslide.css" />
</head>The first line of code represents the main JavaScript file that introduces Highslide, and the second line of code represents the style sheet file that introduces Highslide. These two files must be imported.
Next, you need to define the images to be displayed. The code is as follows:
<body>
<div class="highslide-gallery">
<a href="images/picture1.jpg" class="highslide" onclick="return hs.expand(this)">
<img src="images/picture1_small.jpg" />
</a>
<a href="images/picture2.jpg" class="highslide" onclick="return hs.expand(this)">
<img src="images/picture2_small.jpg" />
</a>
<a href="images/picture3.jpg" class="highslide" onclick="return hs.expand(this)">
<img src="images/picture3_small.jpg" />
</a>
</div>
</body>The above code defines a div named "highslide-gallery", which contains three a tags. Each a tag represents an image to be displayed. Among them, the href attribute represents the path of the original image, and the src attribute in the img tag represents the path of the thumbnail. At the same time, each a tag also needs to add the class="highslide" attribute, which tells Highslide that this is the element to create a picture pop-up effect.
Step 3: Create Highslide configuration file
The Highslide configuration file is written in JavaScript and can set various parameters for the image pop-up effect.
In the root directory of the website, create a JavaScript file named "highslide.config.js" with the following code:
hs.graphicsDir = 'highslide/graphics/'; hs.outlineType = 'rounded-white'; hs.showCredits = false; hs.align = 'center'; hs.marginBottom = 80; hs.marginLeft = 50; hs.marginRight = 50; hs.marginTop = 80;
The above code sets some basic parameters of Highslide, including graphicsDir (Advanced image directory), outlineType (outline type), showCredits (show Highslide logo), align (alignment), marginBottom (bottom margin), marginLeft (left margin), marginRight (right margin) and marginTop (top margin) )wait.
Step 4: Write PHP code
In order to allow high-definition images to be displayed on the page, you need to use PHP to compress the images as needed.
<?php
$image = 'picture1.jpg'; // 原图名称
$width = 800; // 最大宽度
$height = 600; // 最大高度
$quality = 80; // 图片质量
header('Content-Type: image/jpeg');
list($originalWidth, $originalHeight) = getimagesize($image);
$ratio = min($width / $originalWidth, $height / $originalHeight);
$newWidth = $originalWidth * $ratio;
$newHeight = $originalHeight * $ratio;
$newImage = imagecreatetruecolor($newWidth, $newHeight);
$source = imagecreatefromjpeg($image);
imagecopyresampled($newImage, $source, 0, 0, 0, 0, $newWidth, $newHeight, $originalWidth, $originalHeight);
imagejpeg($newImage, null, $quality);
?>In the above code, the original width and height of the image are obtained through the getimagesize function, and then the image is scaled through the imagecopyresampled function, and the image is finally output.
Step 5: Test
Save the above code into a PHP file named "index.php", and then access the file in the browser to see the created image Slide show effect. In Highslide, you can drag with the mouse, zoom in and out with the wheel, etc., which has a better effect on the user experience.
Conclusion
Through the above steps, we can use PHP and Highslide to create a picture slideshow to make the display of website pictures more beautiful and dynamic. At the same time, you can modify it according to your own needs and expand more functions and effects.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
