Therefore, in this article we will explore how to set the roundness of borders in php to make your website more beautiful.

1. Use CSS style sheets to achieve roundness of borders

The PHP language itself does not support directly setting the rounded corners of div or table elements, but by using Cascading Style Sheets (CSS) style sheet to set the border-radius style attribute to achieve a rounded effect. For example, when you apply a style sheet to a div element, add the following CSS property:

border: 2px solid #000;
border-radius: 20px;

This code will add a black border with a thickness of 2 pixels to the border of the div element and set the border's four Each corner shows a rounded effect of 20 pixels. This way you can easily add eye-catching borders to your website.

2. Use third-party libraries to achieve rounded borders

In addition to using CSS style sheets, you can also use third-party libraries to achieve the effect of rounded borders. Among them, Border-Radius Polyfill is a JavaScript library that implements rounded borders in older browsers by combining DIV elements or geometric shapes with SVG images to create rounded angles. It supports all modern browsers and IE 6 and above, and is easy to use. The following is how to call this library:

<script type="text/javascript" src="border-radius.min.js"></script>

After calling the library file, you can use the following style sheet code to call it:

.box {
  width: 200px;
  height: 100px;
  background: #ccc;
  border: 3px solid #c00;
  border-top-left-radius: 20px;
  border-top-right-radius: 10px;
  border-bottom-left-radius: 30px;
  border-bottom-right-radius: 5px;
}

This code will be a DIV element named box Draws rounded borders with different rounding radii. This library makes it quick and easy to give your website beautiful, rounded borders.

3. Use the ImageMagick library to achieve rounded borders

ImageMagick is an open source software suite for image processing that can be used to create and edit a variety of pictures and photos. If you don't want to use CSS and JavaScript to add a rounded border effect, then you can use ImageMagick to achieve this purpose. Here is the code you can use to add rounded borders using the ImageMagick library:

function roundCorners($sourcePath, $cornersize, $borderWidth){
  $imagick = new \Imagick(realpath($sourcePath));
  $imagick-> roundCorners($cornersize,$cornersize,$cornersize,$cornersize);
  $imagick-> borderImage(new \ImagickPixel('white'), $borderWidth, $borderWidth);
  header('Content-Type: image/png');
  echo $imagick;
}

This code will provide you with a roundCorners() method that enables you to specify the original image's URL, rounded corner size, and border width. The method will then use the Imagick library to add rounded borders to the original image. Finally, it will return a PNG format image with a rounded border style in the browser.
