Description
string str_pad (string input, int pad_length [, string
pad_string [, int
pad_type]])
This functions pads the input string on
the left, the right, or both sides to the specifed padding
length. If the optional argument
pad_string is not supplied, the
input is padded with spaces, otherwise it
is padded with characters from pad_string
up to the limit.
Optional argument pad_type can be
STR_PAD_RIGHT, STR_PAD_LEFT, or STR_PAD_BOTH. If
pad_type is not specified it is assumed to
be STR_PAD_RIGHT.
If the value of pad_length is negative or
less than the length of the input string, no padding takes
place.

print str_pad($input, 10, "-=", STR_PAD_LEFT); // produces "-=-=-Alien"
