Handling the Double Quote

[JCScoobyRS]

I am trying to use highlight_string to display PHP code and if the code has any double quotes in it, it gets marked up all wrong. Is there anyway to work around this? Thanks, Jeremy

try an addslashes before you use highlight_string.

Here is what I did to get past the double quote:

PHP Code:

function highlight_code ($langName, $codeText)
    {
        $langName = strtolower($langName);
        require_once XOOPS_ROOT_PATH."/colorcode/HColor_Core.php";
        if ($langName == 'php'){
            $codeText = str_replace('\\','\\\\',$codeText);
            $codeText = highlight_string("<?$codeText?".">", TRUE);
            $codeText = str_replace('\\\\','\\',$codeText);
            return $codeText;
        }else{
            $HColor = new HColorCore;
            $codeText = $HColor->HighlightColor($langName,$codeText);
            return $codeText;
        }
    }

Now, I'm getting this as the output when $codeText = the function:

PHP Code:

function highlight_code ($langName, $codeText)
    {
        $langName = strtolower($langName);
        require_once XOOPS_ROOT_PATH."/colorcode/HColor_Core.php";
        if ($langName == 'php'){
            $codeText = str_replace('\','\\',$codeText);
            $codeText = highlight_string("<?$codeText?".">", TRUE);
            $codeText = str_replace('\\','\',$codeText);
            return $codeText;
        }else{
            $HColor = new HColorCore;
            $codeText = $HColor->HighlightColor($langName,$codeText);
            return $codeText;
        }
    }

On the output...you'll notice that the "\\" became "\" and "\\\\" became "\\". Do you know why this is happening? Thanks, Jeremy

I tried it and found this string worked fine $codetext = '\'\n\r\'';

You have to use the addslashes function to escape the quotes and then it should work.

I'm still new...could you explain a bit more? Thanks alot, Jeremy

[HalfaBee]

You need to add

$codeText = addslashes( $codeText );

before the highlight_string()
and remove the str_replace()'s

I tried that and I'm back to square one. In square one...the markup for the PHP code was all wrong. It had over half of the code that I wanted marked up as a text string (red). Here is the code I'm trying to mark up:

function highlight_code ($langName, $codeText)
    {
        $langName = strtolower($langName);
    	require_once XOOPS_ROOT_PATH."/colorcode/HColor_Core.php";
    	if ($langName == 'php'){
    	    $codeText = str_replace('\\','\\\\',$codeText);
    	    $codeText = highlight_string("<?$codeText?".">", TRUE);
    	    //$codeText = str_replace('\\\\','\\',$codeText);
    	    return str_replace('\"','"',$codeText);
    	}else{
    	    $HColor = new HColorCore;
    	    $codeText = $HColor->HighlightColor($langName,$codeText);
    	    return $codeText;
    	}
    }

This also happens to be the function right now as is. It works for nearly ALL PHP code. When I mark it up the way you suggested, from the end the end of line 4 (require once), all code from "; on that line is red. The way the funtion is now...it marksup properly but it will take the "\\" and turn it into "\" and it will take "\\\\" and turn it into "\\". This isn't a big problem and I could probably deal without fixing it BUT there has to be a way to use highlight_string to beautify ANY PHP code. Right now...I'm having to jump through hoops to do it and the way posted, works if you don't have "\\" or "\\\\". Got anymore ideas? Thanks, Jeremy
