在我的Array中搜索包含特定字符的值

标签： php html

我正在开发一个使用存储在数组中的HTML有效标记的网站，以便与输入系统的用户进行比较。我目前开发了包含我需要的所有HTML标签的数组。我还开发了一个函数，它根据存储在数组中的数据验证用户输入。

如果它有效，那么它将告诉用户它已被接受，然后有效标签将被放入一个包含用户输入的所有标签的不同数组中。

但是我试图创建一种功能，当用户在系统中输入标签时，将搜索数组中包含反斜杠/的任何标签，因为这将识别数组中的所有结束标签。

所以我的问题是如何在AllowedTags数组中提取包含/ Character的所有记录并将它们存储在新数组中。

<html>
<head>
</head>
<body>
<form id="HTMLValidation" method="post" action="<?php echo $_SERVER['PHP_SELF'];?>">
<p> HTML Code: <input type="text" name="code">
<p><input type="submit" name="submit" value="Validate Your Code!"/></p>
</form>
<?php
//Depricated
//$TagArray = $UserInput.split("");
if(isset($_POST['code']))
    {
        $UserInput = htmlspecialchars($_POST['code']);
        $InputtedTags = array();

        //Array Containing all of the VALID HTML TAGS.
        $AllowedTags = array("&lt;html&gt;","&lt;head&gt","&lt;body&gt","&lt;div&gt","&lt;p&gt","&lt;b&gt","&lt;base&gt","&lt;link&gt","&lt;meta&gt","&lt;style&gt","&lt;title&gt","&lt;address&gt","&lt;article&gt","&lt;aside&gt","&lt;footer&gt","&lt;h1&gt","&lt;h2&gt","&lt;h3&gt","&lt;h4&gt","&lt;h5&gt","&lt;h6&gt","&lt;header&gt","&lt;hgroup&gt","&lt;nav&gt","&lt;selection&gt","&lt;dd&gt","&lt;d1&gt","&lt;dt&gt","&lt;figcaption&gt","&lt;figure&gt","&lt;hr&gt","&lt;li&gt","&lt;main&gt","&lt;ol&gt","&lt;pre&gt","&lt;ul&gt","&lt;a&gt","&lt;abbr&gt","&lt;b&gt","&lt;bdi&gt","&lt;bdo&gt","&lt;br&gt","&lt;cite&gt","&lt;code&gt","&lt;data&gt","&lt;dfn&gt","&lt;em&gt","&lt;i&gt","&lt;kbd&gt","&lt;mark&gt","&lt;q&gt","&lt;rp&gt","&lt;rt&gt","&lt;rtc&gt","&lt;ruby&gt","&lt;s&gt","&lt;samp&gt","&lt;small&gt","&lt;span&gt","&lt;strong&gt","&lt;sub&gt","&lt;sup&gt","&lt;time&gt","&lt;u&gt","&lt;var&gt","&lt;wbr&gt","&lt;area&gt","&lt;audio&gt","&lt;img&gt","&lt;map&gt","&lt;track&gt","&lt;video&gt","&lt;embed&gt","&lt;object&gt","&lt;param&gt","&lt;source&gt","&lt;canvas&gt","&lt;noscript&gt","&lt;script&gt","&lt;del&gt","&lt;ins&gt","&lt;caption&gt","&lt;col&gt","&lt;colgroup&gt","&lt;table&gt","&lt;tbody&gt","&lt;td&gt","&lt;tfoot&gt","&lt;th&gt","&lt;thead&gt","&lt;tr&gt","&lt;button&gt","&lt;datalist&gt","&lt;fieldset&gt","&lt;form&gt","&lt;input&gt","&lt;label&gt","&lt;legend&gt","&lt;meter&gt","&lt;optgroup&gt","&lt;option&gt","&lt;output&gt","&lt;progress&gt","&lt;select&gt","&lt;textarea&gt","&lt;details&gt","&lt;dialog&gt","&lt;menu&gt","&lt;menuitem&gt","&lt;summary&gt","&lt;shadow&gt","&lt;slot&gt","&lt;template&gt","&lt;acronym&gt","&lt;applet&gt","&lt;basefont&gt","&lt;big&gt","&lt;blink&gt","&lt;center&gt","&lt;command&gt","&lt;content&gt","&lt;dir&gt","&lt;element&gt","&lt;font&gt","&lt;frame&gt","&lt;frameset&gt","&lt;isindex&gt","&lt;keygen&gt","&lt;listing&gt","&lt;marquee&gt","&lt;multicol&gt","&lt;nextid&gt","&lt;noembed&gt","&lt;plaintext&gt","&lt;shadow&gt","&lt;spacer&gt","&lt;strike&gt","&lt;tt&gt","&lt;xmp&gt","&lt;/html&gt","&lt;/head&gt","&lt;/body&gt","&lt;/div&gt","&lt;/p&gt","&lt;/b&gt","&lt;/base&gt","&lt;/link&gt","&lt;/meta&gt","&lt;/style&gt","&lt;/title&gt","&lt;/address&gt","&lt;/article&gt","&lt;/aside&gt","&lt;/footer&gt","&lt;/h1&gt","&lt;/h2&gt","&lt;/h3&gt","&lt;/h4&gt","&lt;/h5&gt","&lt;/h6&gt","&lt;/header&gt","&lt;/hgroup&gt","&lt;/nav&gt","&lt;/selection&gt","&lt;/dd&gt","&lt;/d1&gt","&lt;/dt&gt","&lt;/figcaption&gt","&lt;/figure&gt","&lt;/hr&gt","&lt;/li&gt","&lt;/main&gt","&lt;/ol&gt","&lt;/pre&gt","&lt;/ul&gt","&lt;/a&gt","&lt;/abbr&gt","&lt;/b&gt","&lt;/bdi&gt","&lt;/bdo&gt","&lt;/br&gt","&lt;/cite&gt","&lt;/code&gt","&lt;/data&gt","&lt;/dfn&gt","&lt;/em&gt","&lt;/i&gt","&lt;/kbd&gt","&lt;/mark&gt","&lt;/q&gt","&lt;/rp&gt","&lt;/rt&gt","&lt;/rtc&gt","&lt;/ruby&gt","&lt;/s&gt","&lt;/samp&gt","&lt;/small&gt","&lt;/span&gt","&lt;/strong&gt","&lt;/sub&gt","&lt;/sup&gt","&lt;/time&gt","&lt;/u&gt","&lt;/var&gt","&lt;/wbr&gt","&lt;/area&gt","&lt;/audio&gt","&lt;/img&gt","&lt;/map&gt","&lt;/track&gt","&lt;/video&gt","&lt;/embed&gt","&lt;/object&gt","&lt;/param&gt","&lt;/source&gt","&lt;/canvas&gt","&lt;/noscript&gt","&lt;/script&gt","&lt;/del&gt","&lt;/ins&gt","&lt;/caption&gt","&lt;/col&gt","&lt;/colgroup&gt","&lt;/table&gt","&lt;/tbody&gt","&lt;/td&gt","&lt;/tfoot&gt","&lt;/th&gt","&lt;/thead&gt","&lt;/tr&gt","&lt;/button&gt","&lt;/datalist&gt","&lt;/fieldset&gt","&lt;/form&gt","&lt;/input&gt","&lt;/label&gt","&lt;/legend&gt","&lt;/meter&gt","&lt;/optgroup&gt","&lt;/option&gt","&lt;/output&gt","&lt;/progress&gt","&lt;/select&gt","&lt;/textarea&gt","&lt;/details&gt","&lt;/dialog&gt","&lt;/menu&gt","&lt;/menuitem&gt","&lt;/summary&gt","&lt;/shadow&gt","&lt;/slot&gt","&lt;/template&gt","&lt;/acronym&gt","&lt;/applet&gt","&lt;/basefont&gt","&lt;/big&gt","&lt;/blink&gt","&lt;/center&gt","&lt;/command&gt","&lt;/content&gt","&lt;/dir&gt","&lt;/element&gt","&lt;/font&gt","&lt;/frame&gt","&lt;/frameset&gt","&lt;/isindex&gt","&lt;/keygen&gt","&lt;/listing&gt","&lt;/marquee&gt","&lt;/multicol&gt","&lt;/nextid&gt","&lt;/noembed&gt","&lt;/plaintext&gt","&lt;/shadow&gt","&lt;/spacer&gt","&lt;/strike&gt","&lt;/tt&gt","&lt;/xmp&gt");

如果用户提供没有尖括号的标签并且只写了标签名称（比如“head”），那么也许你可以在搜索结束标签时在用户输入字符串的开头连接一个反斜杠（） $ AllowedTags。 如果我误解了这个问题，我很抱歉。
