1. strr(i)pos() now uses the full needle when searching - be aware that code that previous have run now can stop working.
EX :
<?php
var_dump(strrpos("ABCDEF","DEF"));
var_dump(strrpos("ABCDEF","DAF"));
?>
Will give you differents results. The diffence is in the second cal to strrpos(). The same applies and for strripos().

2. Change illegal use of string offset from E_WARNING to E_ERROR
3. array_merge() accepts only arrays. If non-array is passed a E_WARNING for every non-array
parameter will be throwed. 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. mysqli_fetch_row()/mysqli_fetch_array()/mysql_fetch_assoc()
retun NULL when there is no more data in the result set (ext/mysql's functions return FALSE).
