PHP

Hello There,

I am trying to Develop a tutorial, and I like to display PHP Code on my page, so user can copy and paste it.

Can any one help me in simple term, how can I print PHP Code on my page, specially color coded (see example below). Any idea With Textarea Box as well as Without Textarea Box will be appreciated.

I like to display PHP Code as its displyed here: This is just an example


<?php

$path = "";
$max_size = 200000;

if (!isset($HTTP_POST_FILES['userfile'])) exit;

?>

replace < and > with < and >

Thanks StarLion, I did not understand your response, by changing < and > displays < and >.

Here I tried Textarea Tag which works; but displyed code are not color coded. Can anyone help, please.

<textarea cols="150" rows="10">
$path = "";
$max_size = 200000;
		
	$res = copy($HTTP_POST_FILES['userfile']['tmp_name'], $path . $HTTP_POST_FILES['userfile']['name']);
	if (!$res) 
	{ 
		echo "upload failed!<br>\
"; exit; } else { echo "upload sucessful<br>\
";
	}
	
	echo "File Name: ".$HTTP_POST_FILES['userfile']['name']."<br>\
";
	echo "File Size: ".$HTTP_POST_FILES['userfile']['size']." bytes<br>\
";
	echo "File Type: ".$HTTP_POST_FILES['userfile']['type']."<br>\
";
</textarea>

Color coding is an entirely different kettle of fish… and about 6 levels of complexity higher.

Not too many standard libraries of languages have this… but you’re in luck!

There’s the javascript syntax highlighter, which has any number of plugins based on it for various languages, CMSes, and libraries/frameworks.

Thank you Force Flow, that is exactly what I need. Simple enough.

Once again, thank you very much.

Hello,

Apply the PHP function “htmlentities” to exchange everything positioned inside the CODEBOX bbcode.
