substr() question

[benrob82]

hi

I am trying to remove the last two digits from a postcode obviously this can be xxxx xxx or xxx xxx

is the best way to remove the last two digits using substr() function and if so how do i do it to remove the last two digits?

Thanks in advance

substr is fine for this.

to get the last two digits:

$postcode = "SW1Y 7GH";
echo "last two digits are: " . substr($postcode, -1, 2);

to get all digits other than the last two digits

$postcode = "SW1Y 7GH";
echo "all but last two digits are: " .substr($postcode, 0, strlen($postcode) - 2);
