PHP converts HTML into text.

In php, the built-in strip_tags function is provided for converting html to text, but sometimes this function is not enough. The following summarizes some user-defined functions for your reference.

The most commonly used php function strip_tags

The Code is as follows:	Copy code
<? Php $ Mystr = <SATO Dozens of lines of HTML code are omitted here. SATO; $ Str = strip_tags ($ mystr ); // Here, I have converted my HTML to TXT text. Haha, this function is really convenient. // The following are some of the plug-in's word splitting operations. ?>

Custom Functions

The Code is as follows:

Copy code

<? Php // $ Document should contain an HTML document. // In this example, the HTML Tag and javascript code are removed. // And blank characters. Some common // Convert the HTML object to the corresponding text. $ Search = array ("'<script [^>] *?>. *? </Script> 'si ", // remove javascript "'<[/!] *? [^ <>] *?> 'Si ", // remove the HTML Tag "'([Rn]) [s] +'", // remove the white space "'& (Quot | #34);' I", // replaces the HTML Object "'& (Amp | #38);' I ", "'& (Lt | #60);' I ", "'& (Gt | #62);' I ", "'& (Nbsp | #160);' I ", "'& (Iexcl | #161);' I ", "'& (Cent | #162);' I ", "'& (Pound | #163);' I ", "'& (Copy | #169);' I ", "'& # (D +); 'E"); // run as PHP code $ Replace = array ("", "", "\ 1 ", """, "&", "<", "> ", "", Chr (1, 161 ), Chr (1, 162 ), Chr (1, 163 ), Chr (1, 169 ), "Chr (\ 1 )"); $ Text = preg_replace ($ search, $ replace, $ document ); ?>

Later, I saw a method written using PHP on the Internet. Using this method can also convert HTML into TXT text. I personally think it is quite practical. Here I will share it with you, the Code is as follows:

The Code is as follows:

Copy code

Function HtmlToText ($ str ){ $ Str = preg_replace ("/<sty (. *)/style> | <scr (. *)/script> | <! -- (. *) -->/IsU "," ", $ str); // remove CSS styles, JS scripts, HTML comments $ Alltext = ""; // variable used to save the TXT text $ Start = 1; // The control switch used to detect the <left,> right label For ($ I = 0; $ I <strlen ($ str); $ I ++) {// traverse each character in the processed string If ($ start = 0) & ($ str [$ I] = ">") {// if the> right tag is detected, use $ start = 1. $ Start = 1; } Else if ($ start = 1) {// screenshot Function If ($ str [$ I] = "<") {// if the character is <left tag, replace it with <font color = 'red' >|</font> $ Start = 0; $ Alltext. = "<font color = 'red' >|</font> "; } Else if (ord ($ str [$ I])> 31) {// if the character is a valid character with ASCII greater than 31, add the character to the $ alltext variable $ Alltext. = $ str [$ I]; } } } // Remove spaces and special characters at the bottom $ Alltext = str_replace ("", "", $ alltext ); $ Alltext = preg_replace ("/& ([^; &] *) (; | &)/", "", $ alltext ); $ Alltext = preg_replace ("/[] +/s", "", $ alltext ); Return $ alltext; }

The preceding method can also be used to convert the simplified HTML code into TXT text.

Example 3

The Code is as follows:

Copy code

Function html2text ($ str, $ encode = 'gb2312 ') { $ 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, $ encode ); $ Str = preg_replace ("/& amp ("/&#.*?; /I "," ", $ str ); Return $ str; }
