I've been trying to add line-numbers to my source code, but can't seem to work out how to do it.
As an example, I tried the following:
<?php
function addPrefix( $matches ) { static $line = 1;
return $line++ . $matches[0]; }
$url = split("\?", $_GET['url']); $source = highlight_file($url[0], true); $source = preg_replace_callback("`\<br \/\>`U", "addPrefix", $source);
echo $source;
?>
which is called whenever the use user on a link like <a href="show-source.php?url=index.php">Show Source</a>
The problem is that my regex does not correcly match the lines.
Anyone got any bright ideas?
This might work :
<style type="text/css">
code { color: rgb(0,0,255) }
.c2 { position:absolute; left:45; white-space: nowrap; }
.nw { white-space: nowrap; }
</style>and then use this function on a file:
function highlight_file_rownums( $file )
{
ob_start();
highlight_file($file);
$data = ob_get_contents();
ob_end_clean();$data_lines = explode('<br />',$data);
for ($i=0, $j=count($data_lines); $i < $j; $i++) {
$k = $i + 1;
$ret .= '<div class="nw"><code>'.$k.'</code><span class="c2">'.$data_lines[$i]."</span></div>\n";
if (strlen($data_lines[$i]) > 450) {
$ret .= '<br />';
}
}
return $ret;
}
