wrong summary Previous Comments: ------------------------------------------------------------------------ [2006-11-03 14:54:41] christoph at ziegenberg dot de Description: ------------ I got a new error message in PHP 5.2 when using mb_strstr() with an empty string as haystack. So I wrote a testfile to compare the behaviour of strstr() with mb_strstr(). Although mbstring function overloading is not enabled and the phpinfo() output (in the same file, so there are no more changes via .htaccess) says that all mbstring settings are the default settings, strstr() is overloaded with mb_strstr(). phpinfo output: --- Multibyte Support enabled Multibyte string engine libmbfl Multibyte (japanese) regex support enabled Multibyte regex (oniguruma) version 4.4.4 Multibyte regex (oniguruma) backtrack check On mbstring extension makes use of "streamable kanji code filter and converter", which is distributed under the GNU Lesser General Public License version 2.1.
