<#
/* JSTE code */
alert('Hello World'
#>
</head>
<body>
<?php
// PHP code
echo 'hello world!';
?>
<%
/* ASP code */
response.write("Hello World!")
%>
<!-- Comments -->
Hello World
</body></html>
Outside HTML
HTML;
$tidy = tidy_parse_string($html
$num = 0;
get_nodes($tidy->html()
function get_nodes($node) {
// check if the current node is of requested type
if($node->isPhp()) {
echo "\n\n# php node #" . ++$GLOBALS['num'] . "\n";
echo $node->value;
}
// check if the current node has childrens
if($node->hasChildren()) {
foreach($node->child as $child) {
get_nodes($child
}
}
}
?>
上面的例子将输出:
# php node #1
<?php echo '<title>title</title>'; ?>
# php node #2
<?php
// PHP code
