dari string kepada date

string to date

Katakan data berbentuk seperti ini

F0003=26031966
F0004=1012010
F0005=31122010

F0003, F0004, F0005 adalah nama medan

cadangnya nak pecahkan jadi seperti ini

F0003=26-03-1966 / 26 Mac 1966
F0004=1-01-2010 / 1 Jan 2010
F0005=31-12-2010 / 31 Dis 2010

Cara pertama 

<?php
echo $var = "1122010"; 
echo '<br>dd-mm-yyyy=' . substr($var,8,2) . ''
. substr($var,6,2) . ''
. substr($var,-4);
echo '<br>';
echo $var = "31122010";
echo '<br>dd-mm-yyyy=' . substr($var,8,2) . ''
. substr($var,6,2) . ''
. substr($var,-4);
?>

output dia
1122010 =>dd-mm-yyyy=11-12-2010
31122010 =>dd-mm-yyyy=31-12-2010

ikutkan 1122012 ada 7 digit kalau boleh nak buat dd-mm-yyyy=1-12-2010

<?php
$input = "1122010";
$len = strlen($input);
if ($len == 6) { $dayLen = 1; $monthLen = 1; $monthStart = 1; } 
else if ($len == 7) {$dayLen = 1;$monthLen = 2;$monthStart = 1;} 
else if ($len == 8) {$dayLen = 2;$monthLen = 2;$monthStart = 1;} 
else { /*throw exception */ }

echo "$input=" . substr($input, 0, $dayLen) 
     . " - " . substr($input, $monthStart, $monthLen) 
     . " - " . substr($input, -4);

$input = "31122010";
$len = strlen($input);
if ($len == 6) { $dayLen = 1; $monthLen = 1; $monthStart = 1; } 
else if ($len == 7) {$dayLen = 1;$monthLen = 2;$monthStart = 1;} 
else if ($len == 8) {$dayLen = 2;$monthLen = 2;$monthStart = 1;} 
else { /*throw exception */ }

echo "<br>$input=" . substr($input, 0, $dayLen) 
     . " - " . substr($input, $monthStart, $monthLen) 
     . " - " . substr($input, -4);

?>

Output
1122010=1 - 12 - 2010
31122010=31 - 11 - 2010
