PHP is a popular scripting language used to develop websites with dynamic web functionality. In PHP, font settings are a very important part as it makes your website more attractive and easy to read. In this article, we will cover how to set fonts in PHP to improve the readability of your website.

1. Use CSS styles to set fonts

In PHP, you can use CSS styles to set fonts. CSS (Cascading Style Sheets) is a standard in web design, which allows developers to more easily control various styles of web pages. Here is some sample code that can be used to set the font by placing it in the head tag of a web page:

In the above code, we are setting the font family of the bodyelement to Arial, Helvetica, sans-serif, this is a universal font family that works well in most browsers. We also set the font size to 16px.

If you want to use a specific font, you can bring it in using the @font-facerule. For example, if you want to use the Roboto font from the Google font library in a web page, you can add the following code in the head tag:

In the above code, we first pass @font-faceThe rules introduce the Roboto font and name it 'Roboto'. Then, we specify the font family of the body element as 'Roboto', sans-serif, where 'sans-serif'is a general font family. We also set the font size to 16px. Please note that it is common for websites to charge for inclusion of this font, so please check for copyright information if you choose to use it.

2. Use HTML tags to set fonts

Similar to CSS styles, you can also use HTML tags to set fonts. Here is some sample code:

 
这是一个标题
 
这是一个段落
 

In the above code, we use the

tag to create a title and set its font family to Arial, Helvetica , sans-serif, this is the same as the previous CSS style setting. We also create a paragraph using the

tag and set the font family to 'Roboto', sans-serifand the font size to 16px. Note that if you use this method to set the font, you will need to add the corresponding style to each element, which may result in some duplicated code and unnecessary work.

3. Use PHP functions to set fonts

PHP provides several functions to set fonts, including functions used when creating images using the GD library. Here are some examples:

1. imagettftext()Function:

Copy after login

In the above code, we first create a 400 pixel wide, 100 pixel high image and set the text color to white. We then specify the font file as arial.ttfand use the imagettftext()function to write the text to the image. Please note that you need to install the GD library and related font files on the server to use this function.

2. pdf_set_font()Function:

AddPage(); $pdf->SetFont('Arial', '', 14); $pdf->Cell(40, 10, '这是一个段落'); $pdf->Output(); ?>

Copy after login

In the above code, we use pdf_set_font()## from the TCPDF library #Function to set font. First, we created a PDF document and created a new page using theAddPage() method. Then, we use theSetFont() method to set the font. Finally, we write text using theCell() method.
