PHP is a popular server-side programming language that is widely used in web development. In web application development, it is often necessary to set and control the display style of text and fonts to improve user experience. This article will discuss how to set font size in PHP.
Generally speaking, the main task of PHP is to process requests on the server and generate HTML. To set the font size, you can use standard HTML/CSS styling settings. The specific method is as follows:
- Use HTML/CSS style sheet to set font size
You can use inline style sheet or external style sheet to set font size. Use an inline stylesheet in HTML tags like this:
<p style="font-size: 16px;">这是一个段落。</p>
Set the font size in an external stylesheet like this:
p {
font-size: 16px;
}
In PHP you can use HTML tags and CSS styles to generate HTML. For example:
Alternatively, use an external style sheet as follows:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="style.css">
</head>
<body>
<?php
echo '<p>这是一个段落。</p>';
?>
</body>
</html>
In this case, the style.css file contains the following style sheet:
p {
font-size: 16px;
}
- Use PHP functions to set font size
In addition to using HTML/CSS style sheets to set font size, you can also use PHP's built-in functions to achieve this. For example, the font size can be set using the following function:
<?php
echo '<p style="font-size:' . fontSize() . 'px;">这是一个段落。</p>';
function fontSize() {
return 16;
}
?>
In this example, the fontSize() function returns 16, which will be used to set the font size of the paragraph.
Font size can be set dynamically using various conditions and calculations. For example, the following function will set the font size based on the $size variable:
<?php
$size = 16;
function fontSize($size) {
return $size;
}
echo '<p style="font-size:' . fontSize($size) . 'px;">这是一个段落。</p>';
?>
