Here's a cheap little function to mimic the print_r() function from PHP in Actionscript. It's designed to work on most any array and will handle nested arrays through recursion.

//
// recursive function to print out the contents of an array similar to the PHP print_r() funciton
//
function print_a( obj, indent ) {
	if (indent == null) indent = "";
	var out = "";
	for ( item in obj ) {
		if (typeof( obj[item] ) == "object" )
			out += indent+"[" + item + "] => Object\n";
		else
			out += indent+"[" + item + "] => " + obj[item]+"\n";
		out += print_a( obj[item], indent+"   " );
	}
	return out;
}
// example call
trace( print_a( example_array ) );

This function will strip out all tabs and return characters. It will also collapse all runs of multiple spaces down to one. It will also remove a leading and trailing spaces. It is similar to the php_strip_whiespace() function in PHP.

function collapseWhiteSpace( theString ) {
	theString =  theString.split("\r").join("");
	theString =  theString.split("\t").join("");
	while ( theString.indexOf("  " ) != -1 ) {
		theString= theString.split("  ").join(" ");
	}
	if (theString.substr(0,1) == " ") {
		theString = theString.substr( 1 );
	}
	if (theString.substr( theString.length-1, 1 ) == " ") {
		theString = theString.substr( 0, theString.length - 1 );
	}
	return( theString );
}

Parse out the body content of an html file. If no tags found, assume whole file is the content to be used.

	$body_content = join( "", file( $file_to_be_read ) );
	if (eregi( "<body.*>(.*)</body>", $t, $regs ) ) {
		$body_content = $regs[0];
	}

Quick and easy way to look up a domain name given an IP address.

dig -x 17.254.3.183

Use the LocalConnection object to get the domain name of the server where the Flash movie is located.

var localDomainLC:LocalConneciton = new LocalConnection();
myDomainName = localDomainLC.domain();
trace( "My domain is " + myDomainName );

This will print out something like this:

My domain is example.com

lsof | grep "Office Server"

Lists out all open files on a given volume ("Office Server" in this case.) Good to find those peskey open files that won't let you eject a mounted network volume.
