Remarks

CSV Parsing is better than simply using Split() on complex data since Split() does not think about finding the split char inside "" quotes etc where as this CSV function does.

Example

A simple split a string using , for the Delimiter

$a = "100, 200, 300";
foreach(CSV($a)[0] as $item)
{
	println("Item '$item'");
}

A more complex split where the , Delimiter is also contained within ' string '

$a = "100, 200, '47, 77', 300, 400, 500";
foreach(CSV($a, ",", "'")[0] as $item)
{
	println("Item '$item'");
}

A larger example involving multiple lines of text to parse and the , Delimiter is also contained within ' string '

$a =  "100, 200, '47, 77', 300, 400, 500\n";
$a .= "122.33 'hello, yay', 55, 77\n";
$a .= "a, b, c, d";
foreach(CSV($a, ",", "'") as $lines)
{
	println("ROW BEGINS");
	foreach($lines as $item)
	{
		println("Item '$item'");
	}
	println("ROW ENDS");
}
