PHP入门笔记
第一个HelloWorld：<html>
<head>
<title>PHP 测试</title>
</head>
<body>
<?php echo '<p>Hello World</p>'; ?>
</body>
</html>
用for循环输出10个helloworld：
<?php
header("Content-Type: text/html; charset=gb2312");
for ($i = 0; $i < 10; $i++) {
echo $i . " Hello World!!</br>";
}
?>
HTML与PHP脚本交叉显示：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=gb2312">
<title>demo</title>
</head>
<body>
<?php
header("Content-Type: text/html; charset=gb2312");
for ($i = 0; $i < 10; $i++) {
?>
Hello World!!<\br>
<?php
}
?>
</body>
</html>
声明PHP脚本方式：
<?php
echo 'if you want to serve XHTML or XML documents, do like this</br>';
?>
<script language="php">
echo 'some editors (like FrontPage) don\'t like processing instructions';
</script>
