How to automatically generate a set of radio buttons with PHP

This article mainly introduces how to use PHP to automatically generate a set of radio selection codes.

The main idea is: use php to form the html code that creates the radio button, and return it to the browser, and the browser can parse the html code.

Code sample:

<?php 
	header(&#39;Content-type:text/html; charset=utf-8&#39;);
	// 编写函数实现自动生成一组单选按钮
	function radioFun($arr, $name, $checked) {
		// 定义保存html代码的变量
		$html = &#39;&#39;;
		foreach ($arr as $key => $value) {
			# 遍历数组,分别形成不同的单选框html代码
			if ($checked == $value) {
				// 若默认选中的值遍历到了,则形成下述html代码
				$html .= "<input type=\"radio\" name=\"$name\" checked=\"checked\" >$value";
			} else {
				// 若不是默认选中的值,则形成如下普通单选框html代码
				$html .= "<input type=\"radio\" name=\"$name\" >$value";
			}
		}
		// 返回完整的html代码交由浏览器解析
		return $html;
	}

	// 测试数据
	$color = array("红色", "黑色", "绿色", "蓝色");
	echo radioFun($color, "color", "绿色");
?>
