PHP convert html to sample, & gt; to> etc.

Question

I want to convert all html tags (& nbsp & gt & lt, etc.) to text format; I tried

html_entity_decode() 

but will he come back? if & nbsp.

Answer 1

Using htmlspecialchars_decode is the opposite of htmlspecialchars .
An example on the PHP documentation page:

  $str = '<p>this -&gt; &quot;</p>'; echo htmlspecialchars_decode($str); //Output: <p>this -> "</p> 

Answer 2

html_entity_decode () is the opposite of htmlentities () in that it converts all HTML objects to string to their applicable characters.

 $orig = "I'll \"walk\" the <b>dog</b> now"; $a = htmlentities($orig); $b = html_entity_decode($a); echo $a; // I'll &quot;walk&quot; the &lt;b&gt;dog&lt;/b&gt; now echo $b; // I'll "walk" the <b>dog</b> now 

Answer 3

Use

  html_entity_decode () 

instead

  html_entity_encode () 

Answer 4

If you check the html_entity_decode () manual:

You may wonder why trim (html_entity_decode ('')); do not reduce the string to an empty string, because the `` object is not ASCII 32 code (which is split using trim ()), but ASCII code 160 (0xa0) in the standard ISO 8859-1 character set.

You can insert the html_entity_decode () function inside str_replace () in ASCII # 160 into space:

 <?php echo str_replace("\xA0", ' ', html_entity_decode('ABC &nbsp; XYZ') ); ?> 

Answer 5

I know that my answer comes very late, but I thought it could help someone else. I believe the best way to extract all special characters is to use utf8_decode () in php. Even for working with   or any other special character using space, use utf8_decode() .

After using utf8_decode() you can manipulate these characters directly in the code. For example, in the following code, the clean () function replaces   empty. Then it replaces all the extra spaces with a single space using preg_replace() . Leading and trailing spaces are removed using trim() .

 function clean($str) { $str = utf8_decode($str); $str = str_replace(" ", "", $str); $str = preg_replace("/\s+/", " ", $str); $str = trim($str); return $str; } $html = "      Hello world! lorem ipsum."; $output = clean($html); echo $output; 

Hello World! lorem ipsum.
