[Resolved] [Resolved] highlight_string

[Shaped]

Hello People..
Got a small problem with highlighted code jumping outside of a table it is being told to display in.
the hilighted code displays fine but it shows above the table it should be wrapped in.

the elseif statement works ok, if HTML is selected the string is returned in the table where it should be...

ive uploaded a ss to show whats happening.
thanku..

	function show_article()
	{
	$id = 1;
		$sql = "SELECT id,article_title,article_article,article_by,article_date,article_type FROM members_articles WHERE id='$id' LIMIT 1";
		$res = mysql_query ( $sql ) or die ( " E1 " . mysql_error () );
		if ( $res ) 
		{
			while ($row = mysql_fetch_row ( $res ) )
			{
			extract ( $row );
				$content = '';
				$content .= '<table id="content3" width="100%" border="1" cellspacing="0" cellpadding="0">';
  				$content .= '<tr><td colspan="2">';
				$content .= $row[1];
				$content .= '</td></tr>';
  				$content .= '<tr><td colspan="2">';
				if ($row[5] == "PHP")
				{

				$content .= highlight_string($row[2]);
			}
			elseif ($row[5] == "HTML")
			{
				$content .= htmlentities($row[2]);
			}
			$content .= '</td></tr>';
			$content .= '<tr><td width="45%">Posted By: '.$row[3].'</td><td width="55%">Date-Submitted: '.$row[4].'</td></tr>';
			$content .= '</table>';

		}
	return ($content);
	}
	else
	{
		echo "(ERROR E1)";
	}


}

[man]highlight_string[/man]
If the second parameter return is set to TRUE then highlight_string() will return the highlighted code as a string instead of printing it out. If the second parameter is not set to TRUE then highlight_string() will return TRUE on success, FALSE on failure.

Which also explains where the '1' is coming from. That's what TRUE looks like when it's cast to a string.

well ive tryed and read that quote from php.net but all i get is

Warning: Wrong parameter count for highlight_string() in /home/sagez/public_html/article.php on line **

ive tryed
$content .= highlight_string($row[2], true);
$content .= highlight_string($row[2], false);

$go = $row[2];
$content .= highlight_string($go);
$content .= highlight_string($go, false);
$content .= highlight_string($go, true);

both return the same error, Ive checked the examples on php.net and my syntax is correct as far as i can see,
Im sure i had this problem somewhere else in a script i made, but carnt think which one it was. It was not to do with highlighting code but with returning data..I did manage to fix that 1, but not this.

from the php manual for highlight_string()

" Note: The return parameter became available in PHP 4.2.0. Before this time it behaved like the default, which is FALSE "

if you need to capture the output into a string and your using an old version of php, use output buffering

ob_start();
highlight_string($foo);
$content = ob_get_contents();
ob_end_clean();

hate to do it to you again, but im gonna 😃

php manual said

" Output buffers are stackable, that is, you may call ob_start() while another ob_start() is active. Just make sure that you call ob_end_flush() the appropriate number of times. If multiple output callback functions are active, output is being filtered sequentially through each of them in nesting order."

works:

<?php


ob_start();
echo 'part 1';

ob_start();
echo 'part 2';

ob_start();
echo 'part 3';

$part3 = ob_get_contents();
ob_end_clean();

$part2 = ob_get_contents();
ob_end_clean();

$part1 = ob_get_contents();
ob_end_clean();


echo "$part2$part3$part1";

?>

thanku for that..

seem to of sorted it now..

ive put it into a function and now its displaying where it should in the table.

function hilight_str($str)
{
	ob_start();
	$go ='';
	$go .= highlight_string($str);
	$goi = ob_get_contents();
	ob_end_clean();
	return ($goi);
}
