The PHP 3.0 Apache module no longer supports Apache versions
prior to 1.2. Apache 1.2 or later is required.
echo() no longer
supports a format string. Use the
printf() function instead.
In PHP/FI 2.0, an implementation side-effect caused
$foo[0] to have the same effect as
$foo. This is not true for PHP 3.0.
Reading arrays with $array[] is no longer
supported
That is, you cannot traverse an array by having a loop that does
$data = $array[]. Use
current() and next()
instead.
Also, $array1[] = $array2 does not append the
values of $array2 to $array1,
but appends $array2 as the last entry of
$array1. See also multidimensional array
support.
"+" is no longer overloaded as a
concatenation operator for strings, instead it converts it's
arguments to numbers and performs numeric addition. Use
"." instead.
Example A-11. Migration from 2.0: concatenation for strings
echo "1" + "1";
In PHP 2.0 this would echo 11, in PHP 3.0 it would echo 2. Instead
use:
