Gat all html from string?

jmansa

I have a string like this:

$txt = '<div>This is a test</div>';

Now when I echo this I get this:
This is a test

What I want is to get all of it like this:
<div>This is a test</div>

Is that possible?

Thanks in advance ;-)

No, you don't; PHP will output the string exactly as you've defined it.

Perhaps you're viewing this output in a web browser (which is going to render that output as HTML, naturally)?

Thats correct... But the problem is more complex than that. I'm trying to do this:

I'm making a sort of a regex script where I want to get the text between some tags using this function:

function get_string_between($string, $start, $end){
	$string = " ".$string;
	$ini = str_get_html($string,$start);
	if ($ini == 0) return "";
	$ini += strlen($start);
	$len = strpos($string,$end,$ini) - $ini;
	return substr($string,$ini,$len);
}

$regstart = '<div>';
$regend = '</div>';

$txt = '<div>This is a test</div>';

$content = get_string_between($txt, $regstart, $regend);

echo 'Content: '.$content;

I dont get the regstart and regend sent correctly? Please help...

Can you show us the definition of the str_get_html() function?

EDIT: Regardless..

Don't. Using regular expressions to sift through HTML is error-prone and just plain not good. Instead, consider using something like [man]DOM[/man] that understands what HTML is and can actually parse it to get the information you need.

At any rate, the function you use to convert it all to useless text (not HTML) is htmlentities...

<?php echo(htmlentities('<div>this text</div>')); ?>

A typo... It should be: strpos

Still no luck!?!?!

[man]htmlentities/man actually gives you HTML back; if it wasn't HTML, then why would '<' become '<' (which is an HTML escape sequence)?

That's why the OP really needs to clarify what "get" means, because there's a difference between what you want PHP to output and what you want to see in a web browser if the output is rendered as HTML.

This:

function get_string_between($string, $start, $end){ 
    $string = " ".$string; 
    $ini = strpos($string,$start); 
    if ($ini == 0) return ""; 
    $ini += strlen($start); 
    $len = strpos($string,$end,$ini) - $ini; 
    return substr($string,$ini,$len); 
} 

$regstart = '<div>'; 
$regend = '</div>'; 

$txt = '<div>This is a test</div>'; 

$content = get_string_between($txt, $regstart, $regend); 

echo 'Content: '.$content;

outputs this:

Content: This is a test

which appears to be exactly what is expected.

So... what's the problem?

Well, I leaned a lesson for my next thread :-( Allway show all...

This is correct... It works with this but when I try to get the regstart and regend from a db table like this:

$sql = mysql_query("SELECT * FROM pages WHERE id=1");
$row = mysql_fetch_assoc($sql);

$regstart = $row['regxstart'];
$regend = $row['regxend'];

Now it doesnt work... The columnfields in the db is varchar... any ideas? And sorry...

EDIT: Sorry again... A typo in my db... Everything works just fine... Sorry and many thanks :-)

It doesn't matter where the strings come from, because in the end they are just strings. As such, if it "doesnt[sic] work," then that simply means that your string values are wrong.

dylanmhulderman

function striphtml_pbcom($string) {
 $rstring = '';
 $inside_tag = false;
 $inside_quo = false;
 for($a = 0;$a < strlen($string);$a++) {
  if($inside_tag) {
   if($inside_quo) {
    if(($string{$a} == '"' || $string{$a} == '\'') && $string{$a - 1} != '\\') {
     $inside_quo = false;
    }
   }
   else {
    if(($string{$a} == '"' || $string{$a} == '\'') && $string{$a - 1} != '\\') {
     $inside_quo = true;
    }
   }
   if(!$inside_quo) {
    if($string{$a} == '>') {
     $inside_tag = false;
    }
   }
  }
  else {
   if($string{$a} == '<') {
    $inside_tag = true;
   }
   else {
    $rstring .= $string{$a};
   }
  }
 }
 return($rstring);
}

That function should work perfectly, the only thing is you need to make sure you HTML syntax is perfect otherwise it will mess up around quotes... See my function actually removes all HTML code based on the < > tags and the ' " quotes... if a < > is inside of quotes, then it will not count that part "asdf<asdf>sadf" as a tag, but will count the <div style="asdf<asdf>sadf"> as a tag and remove it...
