wrong in extensions

[temiz]

hello

my extent in map file:
EXTENT 419630 4510820 516250 4617510

my unzoomed -initial extent in php file gives:
Array ( [0] => 414562.225 [1] => 4510820 [2] => 521317.775 [3] => 4617510 )

could you possibly tell me why x values are different, but y are same  ?
how can I make correction on x values ?
should x values in array same as in map file EXTENT ?

kind regards

Ahmet Temiz
