1. strrpos() and strripos() now use the entire string as a needle.
|
|
Be aware that the existing scripts may no longer work as you expect.
|
|
|
|
EX :
|
|
<?php
|
|
var_dump(strrpos("ABCDEF","DEF"));
|
|
var_dump(strrpos("ABCDEF","DAF"));
|
|
?>
|
|
|
|
Will give you different results. The former returns 3 while the latter
|
|
returns false rather than the position of the last occurrence of 'D'.
|
|
The same applies to strripos().
|
|
|
|
2. Illegal use of string offsets causes E_ERROR instead of E_WARNING.
|
|
|
|
EX :
|
|
<?php
|
|
$a = "foo";
|
|
unset($a[0][1][2]);
|
|
?>
|
|
|
|
Fatal error: Cannot use string offset as an array in ... on line 1
|
|
|
|
3. array_merge() was changed to accept only arrays. If a non-array variable is
|
|
passed, a E_WARNING will be thrown for every such parameter. Be careful
|
|
because your code may start emitting E_WARNING out of the blue.
|
|
|
|
4. Be careful when porting from ext/mysql to ext/mysqli. The following
|
|
functions return NULL when no more data is available in the result set
|
|
(ext/mysql's functions return FALSE).
|
|
|
|
- mysqli_fetch_row()
|
|
- mysqli_fetch_array()
|
|
- mysqli_fetch_assoc()
|
|
|
|
5. PATH_TRANSLATED server variable is no longer set implicitly under
|
|
Apache2 SAPI in contrast to the situation in PHP4, where it is set to the
|
|
same value as the SCRIPT_FILENAME server variable when it is not populated
|
|
by Apache. This change was made to comply with the CGI specification.
