Example of PHP converting HTML into plain text content

We can use many methods to convert html to plain text. However, the simplest method is to use the strip_tags function. However, some friends may find that they can filter out html by using a user-defined function.

However, the simplest method is to use the strip_tags function. However, some friends may find that they can filter out html by using a user-defined function. The following describes some methods.

Convert HTML to plain text: sometimes you may need to convert HTML to plain text. you can use the strip_tags () function to delete all HTML and PHP tags in the string, only text entities are left, in the form:

String strip_tags (string str [, string allowable_tags])

The optional allowable_tags parameter 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:

$ Input = "Email example@example.com"; echo strip_tags ($ input); This returns the following result: the example below in the e-mail example@example.com deletes all the tags outside of the tag: $ input = "This example is yanshare! "; Echo strip_tags ($ input," "); // The Returned result is as follows: This example is yanshare! In PHP
The code is as follows: function br2nl ($ text) {return preg_replace ('/
 
  
/I ', '', $ text);} // Or: function br2nl ($ text) {$ text = preg_replace ('/
  
   
/I ', chr (13), $ text); return preg_replace (' // I ', '', $ text );}
  
 

The code is as follows:

 ] *. *? Script 'Si ", // remove javascript" '<[/!] *? [^ <>] * 'Si ", // remove the HTML tag" '([rn]) [s] + '", // remove the blank character "'& (quot | #34);' I", // replace the HTML entity "'& (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 $ replace = array (" "," "," 1 "," \ "", "&", "<", "> ","",

Chr (1, 161 ),

Chr (1, 162 ),

Chr (1, 163 ),

Chr (1, 169 ),

"Chr (1 )");

$ Text = preg_replace ($ search, $ replace, $ document );

 
// 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.
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:
Function HtmlToText ($ str) {$ str = preg_replace ("/
  
   
|
   
    
|
    /IsU "," ", $ str); // remove CSS styles, JS scripts, HTML comments $ alltext = ""; // The variable $ start = 1 used to save the TXT text; // used for detection
    <左、>
     
Right tag control switch 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; enable the capture function $ start = 1;} else if ($ start = 1) {// truncation 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] ;}}// the following operations remove spaces and special characters $ 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 to TXT text.
