I found myself wanting to parse a CSV and didn't have access to str_getcsv, so I wrote substitute for PHP <= 5.3, hope it helps someone out there stuck in the same situation.

<?php
if (!function_exists('str_getcsv')) {
	function str_getcsv($input, $delimiter = ',', $enclosure = '"', $escape = '\\', $eol = "\n") {
		if (is_string($input) && !empty($input)) {
			$output = array();
			$tmp    = preg_split("/".$eol."/",$input);
			if (is_array($tmp) && !empty($tmp)) {
				while (list($line_num, $line) = each($tmp)) {
					if (preg_match("/".$escape.$enclosure."/",$line)) {
						for ($i=0;$i<strlen($line);$i++) {
							$pos_delimiter		 = strpos($line,$delimiter);
							$pos_enclosure_start = strpos($line,$enclosure);
							if ($pos_enclosure_start < $pos_delimiter) {
								$enclosed_str = substr($line,1);
								$pos_enclosure_end = strpos($enclosed_str,$enclosure);
								$enclosed_str = substr($enclosed_str,0,$pos_enclosure_end);
								$output[$line_num][] = $enclosed_str;
								$offset = $pos_enclosure_end+3;
							} else {
								$output[$line_num][] = substr($line,0,$pos_delimiter);
								$offset = $pos_delimiter+1;
							}
							$line = substr($line,$offset);
						}
					} else {
						$output[$line_num] = preg_split("/".$delimiter."/",$line);
					}
				}
				return $output;
			} else {
				return false;
			}
		} else {
			return false;
		}
	}
}
?>
