can someone tell me if there is posibility to use one pattern for multiple replacement?I have a pattern, and a replacement array and I seek to replace the matches sequentially from the array. Like match = > array[0] match = > array[1] and so on. Thanks

I'd go with a preg_replace with callback:
preg_replace_callback('/pattern/', function () {
static $replacements = array('foo', 'bar', 'baz');
return array_shift($replacements);
}, $subject);
Each subsequent match will get the next entry from the replacement array.

one more moment, how not to make static array in the callback function but pass it via parameter? when I pass my array like
preg_replace_callback($pattern,function($arr){ .... },$subject); I get the same values as were before.??

You'd use the closure aspect to do that:
..., function () use ($arr) { ... }, ....Vit Kos
thanks, that means I can use something like
...,function() use ($arr){ return array_shift($arr);},.... ?
