Well I created this simple script to help someone else on the site, figured I'd put it in its own thread. It basically uses the the PHP function highlight_file() to perform the standard PHP syntax highlighting. However, the limitation is that it didn't have line numbers. So I tweaked the output of that function a bit in order to also output line numbers.[PHP]<pre>
<?php
$filename = 'forum/admin.php';
ob_start();
highlight_file($filename);
$source = ob_get_contents();
ob_end_clean();
$source = explode(chr(13), $source);
$temp = substr($source[0], 0, 35);
$temp .= substr($source[0], 36);
$source[0] = substr($temp, 6);
$temp = substr($source[count($source) - 1], 0, strlen($source[count($source) - 1]) - 8);
$source[count($source) - 1] = $temp;
for($i = 1; $i < count($source); $i++){
$source[$i] = substr($source[$i], 6);
}
for($i = 0; $i < count($source) - 1; $i++){
$source[$i] .= '<br />';
}
$spaces = strlen(count($source));
for($i = 0; $i < count($source); $i++){
$source[$i] = '<span style="color: #777777">' . ($i + 1) . '</span> ' . $source[$i];
for($j = 0; $j < $spaces - strlen($i + 1); $j++){
$source[$i] = ' ' . $source[$i];
}
}
for($i = 0; $i < count($source); $i++){
echo $source[$i];
}
?>
</pre>[/PHP]

Nice script, very useful =D

except when I run it as-is, the first line, <?php, is on the second line uncounted and line 1 is left blank

so I went ahead and made an attempt somewhat based on your script:
[php]<?php
$file = 'script.php';

ob_start();
highlight_file($file);
$source = ob_get_contents();
ob_end_clean();

echo '<pre>';
$blocks = explode("\n", $source);
$lines = str_replace(' ', ' ', explode(chr(13), $blocks[1]));
for ($i = 0; $i < count($lines); $i++)
{
for ($j = 0; $j < strlen(count($lines)) - strlen($i + 1); $j++)
{
echo ' ';
}
$lines[$i] = (($i == 0) ? '<br />' : '') . $lines[$i];
echo '<span style="color: #777777">' . ($i + 1) . '</span> ' . substr($lines[$i], 6) . "\n";
}
echo '</pre>';
?>[/php]
Notes:
replacing   with a space reduces the file size

also, there seems to be a difference between "\n" and chr(13) from highlight_file, so splitting it into blocks first with "\n" will let you get what you want (the content itself) to split it with chr(13), which removes that first extra new line.

I don't quite understand what you mean about the output of my script Styx, could you possibly post the output so I can get a better idea?

I'm not sure why yours isn't getting the same thing. But your code also produced proper output so whatever works ^_^. Also, the idea behind using &nbsp instead of the space character is so that rather than using the pre html tag the user can use a span with another monospaced font. For instance, something like this: <span style="font-family: Courier New; font-size: 10pt"> which produces the same results.

grimpirate · Mar 19th, 2007, 1:36 PM

I improved the code to be able to select only the source code without the line numbers getting selected:[PHP]<html>

$temp .= substr($source[0], 36);
$source[0] = substr($temp, 6);
$temp = substr($source[count($source) - 1], 0, strlen($source[count($source) - 1]) - 8);
$source[count($source) - 1] = $temp;
for($i = 1; $i < count($source); $i++){
$source[$i] = substr($source[$i], 6);
}
for($i = 0; $i < count($source) - 1; $i++){
$source[$i] .= '<br />';
}
$lineNum = array();
$spaces = strlen(count($source));
for($i = 0; $i < count($source); $i++){
array_push($lineNum, '<span style="color: #777777">' . ($i + 1) . '</span> ');
for($j = 0; $j < $spaces - strlen($i + 1); $j++){

ooo, nice improvement ^_^

The first line doesn't seem to highlight properly though. <?php tags are black if they're at line 1, and, when it scans your script, <html> turns into <htl>

grimpirate · Mar 19th, 2007, 3:34 PM

I remade the code and cut it down so it would be less memory intense by replacing some style codes with a main style sheet and also used css to control the spacing of the line numbers to decrease the number of &nbsp's that were necessary. The ones in the sourcecode still remain. Also, when there was a linewrap this would produce errors so I imposed a no linewrapping property in the style. However, this ONLY works in FIREFOX. For whatever reason Internet Explorer chooses to mess up the css as it sees fit.[PHP]<html>

DaWei · Mar 19th, 2007, 4:00 PM

Whether or not a line ending is 10, 13, or a combination of both depends on the platform. Windows files may, all by their li'l selves, have either a 10 or a 13+10. You might want to see if that's giving you a problem on the explode.

'<br />' : '') . $lines[$i]; echo '<span style="color: #777777">' . ($i + 1) . '</span> ' . substr($lines[$i], 6) . "\n"; } echo '</pre>'; ?>[/php] Notes: replacing   with a space reduces the file size also, there seems to be a difference between "\n" and chr(13) from highlight_file, so splitting it into blocks first with "\n" will let you get what you want (the content itself) to split it with chr(13), which removes that first extra new line.

The ones in the sourcecode still remain. Also, when there was a linewrap this would produce errors so I imposed a no linewrapping property in the style. However, this ONLY works in FIREFOX. For whatever reason Internet Explorer chooses to mess up the css as it sees fit.[PHP]<html> <head> <title>Grim PHP Syntax Highlighter</title> <style type="text/css"> body { font-family: Courier New; font-size: 10pt; white-space: nowrap; } div.lineNumbers { float: left; text-align: right; margin-right: 8px; padding-right: 8px; border-right: 1px #999999 solid; color: #777777; } span.v { color: #0000BB; } span.k { color: #007700; } span.s { color: #DD0000; } span.c { color: #FF8000; } </style> </head> <body> <?php $filename = 'forum/board_lib.php'; ob_start(); highlight_file($filename); $source = ob_get_contents(); ob_end_clean(); $source = explode(chr(13), $source); $source[0] = substr($source[0], 36); $temp = substr($source[count($source) - 1], 0, strlen($source[count($source) - 1]) - 15); $source[count($source) - 1] = $temp; for($i = 1; $i < count($source); $i++){ $source[$i] = substr($source[$i], 6); } for($i = 0; $i < count($source) - 1; $i++){ $source[$i] .= '<br />'; } echo '<div class="lineNumbers">' .

It seems like you're always missing a letter somewhere. __________________ Lo, there do I see my father. 'Lo, there do I see My mother, and my sisters, and my brothers.

Windows files may, all by their li'l selves, have either a 10 or a 13+10. You might want to see if that's giving you a problem on the explode. __________________ Abstraction doesn't make it impossible to write bad code; it makes it possible to write superior code.
