For those who do not have php5.3+, here is a php4+
compatible function that will approximate what this
function does. 

NOTE: It does NOT exactly mimic it,
but it should be close enough for most
people's needs.

NOTE: The masks do NOT accurately
reflect the masks used in the date() format.
For simplicity sake they are just generic masks
for each date/time increment in order to parse
the $date string you pass. 

<?php
function date_parse_from_format($format, $date) {
  $dMask = array(
    'H'=>'hour',
    'i'=>'minute',
    's'=>'second',
    'y'=>'year',
    'm'=>'month',
    'd'=>'day'
  );
  $format = preg_split('//', $format, -1, PREG_SPLIT_NO_EMPTY); 
  $date = preg_split('//', $date, -1, PREG_SPLIT_NO_EMPTY); 
  foreach ($date as $k => $v) {
    if ($dMask[$format[$k]]) $dt[$dMask[$format[$k]]] .= $v;
  }
  return $dt;
}
?>

Example 1:

<?php
print_r(date_parse_from_format('mmddyyyy','03232011');
?>

Output 1:

Array
(
    [month] => 03
    [day] => 23
    [year] => 2011
)

Example 2:

<?php
print_r(date_parse_from_format('yyyy.mm.dd HH:ii:ss','2011.03.23 12:03:00'));
?>

Output 2:

Array
(
    [year] => 2011
    [month] => 03
    [day] => 23
    [hour] => 12
    [minute] => 03
    [second] => 00
)

Example of rewriting function for older PHP versions:

convert
April 8, 2009, 1:12 am
to
timestamp

<?php
function date2sql($str = ""){
$month_arr = array (
    "January" => 1,
    "February" => 2,
    "March" => 3,
    "April" => 4,
    "May" => 5,
    "June" => 6,
    "July" => 7,
    "August" => 8,
    "September" => 9,
    "October" => 10,
    "November" => 11,
    "December" => 12
);
preg_match('/([a-zA-Z]{3,9}) ([0-9]{1,2}), ([0-9]{4}),
([0-9]{1,2}):([0-9]{1,2}) ([ap])m/',$str,$matches2);
if ($matches2[6]=="a") $hour = $matches2[4];
else $hour = $matches2[4]+12;
if ($hour==24) $hour=0;
return mktime($hour,$matches2[5],0,
$month_arr[$matches2[1]],$matches2[2],$matches2[3]);
}
    $time = date2sql("March 29, 2009, 12:12 pm");
    echo "{$time}</br>\n";
?>
