strip_tags Removing all html formatted tags from a string

Removing HTML tags by using strip_tag function

We can remove all html tags from the content by using strip_tags string function in PHP. This function can be used to collect only the content part without reading the html formatting of the page. Here is the syntax


 strip_tags (input string [, string allowable_tags])

This function also allows one optional string where we can keep the tags which are not to be removed. Say we don't want the hyper links to be removed. So we will allow the linking tag <a href to be kept as it is. Here is the syntax for this.

strip_tags($string_str, '<a>');

In the above code $string_str is the input string.

Using strip_tags function we can collect content from different pages of a directory. Now let us try to collect the content of a sample page test.php. You can read the tutorial on how to collect content of a page here.

Here is the code to collect the content of the page and then we will apply strip_tags to remove all tags and display only the text content without any HML formatting.


$path="test.php";

$contents="";

$fd = fopen ($path, "r"); // opening the file in read mode

while($buffer = fread ($fd,1024)){

$contents .=$buffer;

}

fclose ($fd);  



$contents=strip_tags($contents,'<a>');

echo $contents;
