ok, it slices and dices, but how?
in python, to print all but the last char in string FOO, we say
print FOO[:-1]
But this seems to bark like a basset hound in php. Whyfore?
Now tihs tyro is seeking sage words to help me understand this.
RTFM is not sage words; if you don't want to help me please don't waste
the bandwidth.
Would anyone care to help me understand this without dedicating 4
precious and in over demand/under supply hours to RTFM?
print substr($foo, 0, -1);
You could also do this, but it takes more code:
print substr($foo, 0, strlen($foo) - 1);
You could wrap it as a function like so:
function strchop($string, $num_chars_to_chop_off_end)
{
return substr($string, 0, -$num_chars_to_chop_off_end);
}
If you have time, the relevant manual page is:
