Code for converting php html format to text format

There are many ways to convert html tags into plain text in php. For example, if php comes with the strip_tags function, it can directly convert html into plain text format, next, let's take a look at various conversion codes.

Let's take a look at the strip_tags () function usage.

In the following example, all tags except the <a> tag are deleted:

The Code is as follows:	Copy code
<! --? Php <br? --> $ Input = "This <a href =" http://www.bKjia. c0m/"> example </a> Is <strong> yanshare </strong>! "; Echo strip_tags ($ input, "<a> "); ? & Gt; </A> Input result This <a href = "http://www.bKjia. c0m/"> example </a> Is yanshare!

The connection and connection content are filtered out. If you want to retain the content in A, refer to the following code:

Strip_tags has an optional parameter allowable_tags, which specifies the tag that can be skipped during this process. The following example uses strip_tags () to delete the HTML tag from the string:

The Code is as follows:	Copy code
<! --? Php <br? --> $ Input = "Email <a href =" example@example.com "> example@example.com </a> "; Echo strip_tags ($ input ); ? & Gt; The following results are returned: Email example@example.com

A custom character set that converts html to a character set without html tags.

The Code is as follows:

Copy code

Function html2text ($ str ){ $ Str = preg_replace ("/<style .*? </Style>/is "," ", $ str); $ str = preg_replace ("/<script .*? </Script>/is "," ", $ str ); $ Str = preg_replace ("/<br s */? />/I "," n ", $ str ); $ Str = preg_replace ("/</? P>/I "," nn ", $ str ); $ Str = preg_replace ("/</? Td>/I "," n ", $ str ); $ Str = preg_replace ("/</? Div>/I "," n ", $ str ); $ Str = preg_replace ("/</? Blockquote>/I "," n ", $ str ); $ Str = preg_replace ("/</? Li>/I "," n ", $ str ); $ Str = preg_replace ("/& nbsp;/I", "", $ str ); $ Str = preg_replace ("/& nbsp/I", "", $ str ); $ Str = preg_replace ("/& amp;/I", "&", $ str ); $ Str = preg_replace ("/& amp/I", "&", $ str ); $ Str = preg_replace ("/& lt;/I", "<", $ str ); $ Str = preg_replace ("/& lt/I", "<", $ str ); $ Str = preg_replace ("/& ldquo;/I", '"', $ str ); $ Str = preg_replace ("/& ldquo/I", '"', $ str ); $ Str = preg_replace ("/& lsquo;/I", "'", $ str ); $ Str = preg_replace ("/& lsquo/I", "'", $ str ); $ Str = preg_replace ("/& rsquo;/I", "'", $ str ); $ Str = preg_replace ("/& rsquo/I", "'", $ str ); $ Str = preg_replace ("/& gt;/I", ">", $ str ); $ Str = preg_replace ("/& gt/I", ">", $ str ); $ Str = preg_replace ("/& rdquo;/I", '"', $ str ); $ Str = preg_replace ("/& rdquo/I", '"', $ str ); $ Str = strip_tags ($ str ); $ Str = html_entity_decode ($ str, ENT_QUOTES, "UTF-8 "); $ Str = preg_replace ("/& amp ("/&#.*?; /I "," ", $ str ); Return $ str; }
