Numbered Code Highlighter (Rated 5)


This will hightlight the php code and number each line. This can be initiated in many different ways. The function colorphp has a first argument that accepts the string to highlight, and the second argument accepts an int that will declare what the numbers should start as.
A simple way to implement the script is using regex, like this:

Code starts here

function colorphp($var,$start=1){
$x=explode("<br />",highlight_string($var,true));
$v.="\n<font face='verdana' size='1' color='#000000'><strong>".$start.":</strong></font> ".$x[$i]."\n<br />";
$t='<table width="100%" cellpadding="2" cellspacing="0">';
$t.="\n<tr valign='top'>";
$t.="\n<td><span class=\"med\">PHP:</span></td>";
$t.="\n<tr valign='top'>";
$t.="\n<td><p class='code'>{$v}</p></td>";
could be called like so.
//1st method
$text="\ntesting \n<?\necho 'hello';\n?>\n yep";
//Will ouput the following, but colored
1: testing
2: <?
3: echo 'hello';
4: ?>
5: yep
//2nd method
$text="\ntesting \n<?\necho 'hello';\n?>\n yep";
//Will ouput the following, but colored
3: testing
4: <?
5: echo 'hello';
6: ?>
7: yep
//3rd method
$text="\ntesting \n<?\necho 'hello';\n?>\n yep";
//Will ouput the following, but only the text on lines 2-4 would be colored.
1: testing
2: <?
3: echo 'hello';
4: ?>
5: yep
