[SOLVED] trim and replace help on certain text

[jesushax]

ok so heres my example

<p>
Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Suspendisse purus enim, gravida et, dictum sed, cursus id, tellus
</p><p><br />
Nunc sodales consequat dui. Pellentesque faucibus ligula et dui. Suspendisse potenti. Vivamus sit amet ligula. Aenean pulvinar imperdiet enim. Nam aliquam purus. 
</p>

 

 

the paragrahs and breaks will be in different positions sometimes

 

but what i want to do is remove all <br /> from the submitted text

 

and remove the the <p> if the submitted text begins with one and remove the </p> if the submitted text ends with one

 

and only keep </p><p> if there is one

 

so

remove all <br />

remove first <p>

remove last </p>

keep </p><p>

 

cheerss

I'm sure there's an easier way, but I like complex (call me a freak.....)

<?php
$code="Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Suspendisse purus enim, gravida et, dictum sed, cursus id, tellus
</p><p><br />
Nunc sodales consequat dui. Pellentesque faucibus ligula et dui. Suspendisse potenti. Vivamus sit amet ligula. Aenean pulvinar imperdiet enim. Nam aliquam purus. 
</p>";
$code = str_replace("<br />", "", $code);
$code_array = str_split($code);
$code_count = count($code_array);
$count = $code_count - 4;
$count_p = $count++;
if ($code_array[0] == "<" && ($code_array[1] == "p" || $code_array[1] == "P")){
unset($code_array[0]);
unset($code_array[1]);
unset($code_array[2]);
$code_count = count($code_array);
$count = $code_count - 1;
if ($code_array[$count] == "<" && $code_array[$count + 1] == "/"){
	unset($code_array[$code_count]);
	++$code_count;
	unset($code_array[$code_count]);
	$code_count++;
	unset($code_array[$code_count]);
	$code_count++;
	unset($code_array[$code_count]);
	array_pop($code_array);
}
$code = implode($code_array);
}

elseif ($code_array[$count - 1] == "<" && $code_array[$count] == "/"){
	array_pop($code_array);
	array_pop($code_array);
	array_pop($code_array);
	array_pop($code_array);
	$code = implode($code_array);
}
print $code;
?>

<pre>
<?php
$data = <<<DATA
<p>
Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Suspendisse purus enim, gravida et, dictum sed, cursus id, tellus
</p><p><br />
Nunc sodales consequat dui. Pellentesque faucibus ligula et dui. Suspendisse potenti. Vivamus sit amet ligula. Aenean pulvinar imperdiet enim. Nam aliquam purus. 
</p>
DATA;

$data = str_replace('<br />', '', $data);
$data = preg_replace('%\A\s*<p>|</p>\s*\z%', '', $data);
echo htmlspecialchars($data);
?>
</pre>
