Php WP HTML缩小类不工作
我在电脑上找到了这个脚本。它应该缩小（而不是像类名建议的那样压缩）HTML：Php WP HTML缩小类不工作,php,regex,wordpress,minify,Php,Regex,Wordpress,Minify,我在电脑上找到了这个脚本。它应该缩小（而不是像类名建议的那样压缩）HTML： 自定义方法怎么样 public static function html_compress($buffer) { $chunks = preg_split( '/(<pre.*?\/pre>)/ms', $buffer, -1, PREG_SPLIT_DELIM_CAPTURE ); $buffer = ''; $replace = array( '#[\n\r\t\
自定义方法怎么样
public static function html_compress($buffer)
{
$chunks = preg_split( '/(<pre.*?\/pre>)/ms', $buffer, -1, PREG_SPLIT_DELIM_CAPTURE );
$buffer = '';
$replace = array(
'#[\n\r\t\s]+#' => ' ', // remove new lines & tabs
'#>\s{2,}<#' => '><', // remove inter-tag whitespace
'#\/\*.*?\*\/#i' => '', // remove CSS & JS comments
'#<!--(?![\[>]).*?-->#si' => '', // strip comments, but leave IF IE (<!--[...]) and "<!-->""
'#\s+<(html|head|meta|style|/style|title|script|/script|/body|/html|/ul|/ol|li)#' => '<$1', // before those elements, whitespace is dumb, so kick it out!!
'#\s+(/?)>#' => '$1>', // just before the closing of " >"|" />"
'#class="\s+#'=> 'class="', // at times, there is whitespace before class=" className"
'#(script|style)>\s+#' => '$1>', // <script> var after_tag_has_whitespace = 'nonsens';
);
$search = array_keys($replace);
foreach ( $chunks as $c )
{
if ( strpos( $c, '<pre' ) !== 0 )
{
$c = preg_replace($search, $replace, $c);
}
$buffer .= $c;
}
return $buffer;
}
公共静态函数html\u compress（$buffer）
{
$chunks=preg_split（'/（）/ms'，$buffer，-1，preg_split_DELIM_CAPTURE）；
$buffer=''；
$replace=数组(
'#[\n\r\t\s]+#'=>''，//删除新行和制表符
“#>\s{2，}#si'=>''，//删除注释，但如果IE（“'
“#\s+”，//就在“>”|“/>结束之前
“#class=”\s+#“=>”class=“”，//有时，class=”className“前面有空格
“#（script | style）>\s+#”=>“$1>”，//标记后的变量有“\u空格='nonsens'”；
);
$search=array\u key（$replace）；
foreach（$c块）
{
如果（strpos，$c，这里还有其他问题
我将这个“类”简化为一个单页PHP脚本（将任何$this->调用替换为true（对于IVAR）或静态函数调用）
然后，我使用长HTML输入运行了各种测试，并尝试使用条件注释进行处理，包括复制粘贴之前的条件标记。每次结果都是一行输出
总之，有一些可能性：
在你的HTML中还有其他东西把它扔了（链接到实际页面？）
缩小是在添加额外HTML之前发生的（很可能）
其中一个IVAR不正确（不太可能）
有东西正在将
插入文档的该部分
为什么不在minifyHTML（$html）方法的开头插入error_log（$html）；
（或类似内容）以查看原始html的外观。我猜，这样做的结果会告诉您它不起作用的原因。（我猜，您也可以返回$html；
）
编辑---
这是我的“脚本”，请注意，保留了条件注释，剥离了非条件HTML注释。我根本不关心行格式，因为这只是您提供的原始类中的一个黑客作业

该网站只是将代码重新命名。不知何故，使用“他们的”代码比使用实际的插件要好？哦，好吧
WordPress和标准PHP都有更新版本：
你实际上是如何使用缩小函数/方法的？是的。IE条件没有缩小。你误解了我。你在哪里调用函数，你的html是什么？WP钩子处理调用。在任何情况下，你都不需要依赖钩子。只需实例化类并传递未经缩小的html。嗯……你的目标是什么未统一的HTML？这与类所做的非常相似。此脚本的源代码是什么？是否有针对它的单元测试？我已经使用了两年。还没有单元测试。源代码是internet和我自己的正则表达式熟练程度。我创建了一个脚本，您可能会问为什么要替换。[\n\r\t\s]+#
只有一个空格？为什么\s{2，}有时候你会有类似于hello world
的东西，所以当你删除空格时，你会得到helloworld
。因此在关闭
后留下一个空格。用一个空格替换回车、制表符和空格可以确保如果你用回车和制表符格式化代码（这确实会导致显示空格）您找不到上面的示例。希望这能澄清一点。欢迎您改进它！：）您的示例hello world
不适用于我询问的任何正则表达式。您关于“输入、制表符和空白带一个空格”的解释对我来说没有意义；为什么不再次替换为空字符串呢？当然，但这将是一个很大的问题，因为我在测试中已经完成了。嗨，史蒂文，你是脚本的原始作者吗？是的，我还在维护它。
