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";
?>
