PHP transforms HTML into text some ways to summarize _php tutorials

In PHP, HTML is converted into text to provide the function strip_tags, but sometimes this function is not enough, the following summarizes some user-defined functions, you can refer to.

The most common use of PHP functions Strip_tags

The code is as follows	Copy Code
$mystr =<<<> Dozens of lines of HTML code are omitted here ^_^ SATO; $str =strip_tags ($MYSTR); Here I have reached the purpose of my HTML into txt text, haha, it is very convenient to use this function Here are some of the plug-in words and other operations, here is not much to say ?>

Custom functions

code as follows

copy code

< p> the!--? php //$document should contain an HTML document. //This example will remove HTML tags, JavaScript code //and white space characters. Some generic //HTML entities are also converted to the appropriate text. $search = Array ("' Si ',//Remove JavaScript " ' <[/!] *? [^<>]*?> ' Si ',//Remove HTML Tags "' ([RN]) [s]+ '",//Remove whitespace characters "' & (quot| #34); ' I ",//Replace 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 As PHP code $replace = Array ("", "," "\1", " " "," "&", "<", ">", "", Ch R (161), Chr (162), Chr (163), Chr (169), "Chr (\1)"); $text = preg_replace ($search, $replace, $document); ?

Later I saw from the Internet a way to write using PHP, using this method can also be implemented to convert HTML to txt text, the personal feel is also quite practical, here to share, the code is as follows:

The code is as follows

Copy Code

function Htmltotext ($STR) { $str =preg_replace ("/ | | /isu "," ", $str);//Remove CSS style, JS script, HTML comment $alltext = "";//variable for saving txt text $start =1;// <左、> Control switch for detecting the right label for ($i =0; $i if ($start ==0) && ($str [$i]== ">") {//if > Right tag is detected, use $start=1; turn on intercept function $start = 1; }else if ($start ==1) {//Intercept function if ($str [$i]== "<") {//If the character is<> $start = 0; $alltext. = "|"; }else if (Ord ($str [$i]) >31) {//If the character is a valid character with ASCII greater than 31, the character is added to the $alltext variable $alltext. = $str [$i]; } } } Below are actions to remove spaces and some special characters $alltext = Str_replace ("", "" ", $alltext); $alltext = Preg_replace ("/& ([^;&]*) (;|&)/", "", $alltext); $alltext = Preg_replace ("/[]+/s", "", $alltext); return $alltext; }

Using this method can also be implemented to convert the simple HTML code to txt text.

Example 3

The code is as follows	Copy Code
function Html2text ($str, $encode = ' GB2312 ') { $str = Preg_replace ("/
