מדריך PHP קודם נספח C. Migrating from PHP / FI 2 to PHP 3 הבא 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. דוגמה C-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: echo "1" ."1"; $a = 1; $b = 1; echo $a + $b; This would echo 2 in both PHP 2.0 and 3.0. $a = 1; $b = 1; echo $a.$b; קודם ראשי הבא Function TRUE / FALSE return values למעלה Debugging PHP
