自己写了个高亮的函数

自己写了个高亮的函数！可以自定义关键字和函数！

[php]
<?php
function highLight($code) {
$config_file = 'config.xml';
$xml = simplexml_load_file("config.xml");
$code = str_replace('>', '>', $code);
$code = str_replace('<', '<', $code);
$code =  str_replace("\t", "    ", nl2br($code));

$k_color = $xml->keywords->attributes();
$k_color = $k_color['color'];
$code = preg_replace("/\"(.{1,})\"/", "<span style=\"color:green;\">\"$1\"</span>", $code);
$code = preg_replace("/([url=file://\\$[0-9a-zA-z_]{1,})/]\\$[0-9a-zA-z_]{1,})/[/url]", "<span style=\"color:#80f;\">$1</span>", $code);
$code = preg_replace("/class\s{1,}([0-9a-zA-Z_]{1,})/", "class <span style=\"text-decoration:underline;\">$1</span>", $code);
foreach($xml->keywords->e as $e) {
  $code = preg_replace("/(\s{0,}$e\s{1,})/", '<span style="color:'. $k_color .";\">\$1</span>", $code);
}
unset($e);

$f_color = $xml->functions->attributes();
$f_color = $f_color['color'];
foreach($xml->functions->e as $e) {
  $code = str_replace($e, '<span style="color:'. $f_color .';">' . $e . '</span>', $code);
}
unset($e);
echo $code;
}
$code = <<<CODE
<?php

private \$name;

  echo "hello world";

public function __construct(\$name) {
  \$this->name = \$name;

不过还是 代码加亮SyntaxHighlighter好

顶起！

不错的说。

不错，赞！
