| Octal and Decimal Numbers | | I am trying to assign a variable the value of 0123,
but it keeps coming up with a different number, what's
the problem? | | By: FYIcenter | If you assign a variable with a value of 0123, PHP
will interpret as an octal number resulting to decimal
value of 83.
All numbers that preceded with a 0 (zero) will be
interpreted as octabl numbers. This is one of the PHP
literal data rules.
For example, the PHP script below will produce: 83 and
123.
<?php
$octal = 0123; // octal number (equivalent to 83
decimal)
$decimal = 123; // decimal number
echo $octal ."\n";
echo $decimal ."\n";
?>
