The most common function of converting html to text using p in php provides the built-in function strip_tags, 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:
$ Mystr = < 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:

// $ 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 '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:

Function HtmlToText ($ str ){ $ Str = preg_replace ("/ | | /IsU "," ", $ str); // remove CSS styles, JS scripts, and HTML comments. $ Alltext = ""; // variable used to save the TXT text $ Start = 1; // used for detection <左、> Control switch of right label For ($ I = 0; $ I 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 <左标签，则使用|替换 $ Start = 0; $ Alltext. = "| "; } 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.

The code is as follows:
Function html2text ($ str, $ encode = 'gb2312 ') { $ Str = preg_replace ("/
