Rather use rtrim(). Usage of chop() is not very clear nor consistent for people reading the code after you.
Nota:
chop() é diferente da função do Perl
chop(), que remove o último caractere da string.
Rather use rtrim(). Usage of chop() is not very clear nor consistent for people reading the code after you.If you are searching for a function that does the same trick as chop in PERL, then you should just do the following code:
<?php
$str = substr($str, 0, -1);
?>
The question is: why isn't chop() an alias of the code above, rather than something which will trap developpers?
