Please provide the short and self-contained example to reproduce the problem. I could never reproduce the problem with the following way. $ env REQUEST_METHOD=get QUERY_STRING=x=%fc SCRIPT_FILENAME=/tmp/test.php php-cgi -c /tmp/test.ini test.php: <?php var_dump($_REQUEST); ?> test.ini: mbstring.encoding_translation=on mbstring.http_input=auto mbstring.internal_encoding=UTF-8 Previous Comments: ------------------------------------------------------------------------ [2008-06-11 15:02:26] pumuckel at metropolis dot de Description: ------------ When mbstring.encoding_translation is set to on, and passing a variable like x=%FC (ISO 'ΓΌ' character) the mb lib is hanging in itself. Following settings are applyied (internal encoding is ISO): Multibyte Support enabled Multibyte string engine libmbfl HTTP input encoding translation enabled 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. Directive Local Value Master Value mbstring.detect_order auto no value mbstring.encoding_translation On Off mbstring.func_overload 0 0 mbstring.http_input UTF-8,ISO-8859-15 pass mbstring.http_output ISO-8859-15 pass mbstring.internal_encoding ISO-8859-15 no value mbstring.language neutral neutral mbstring.strict_detection On Off mbstring.substitute_character no value no value Also not working with these settings (internal UTF8) mbstring.detect_order auto auto mbstring.encoding_translation On On mbstring.func_overload 0 7 mbstring.http_input UTF-8,ISO-8859-15 auto mbstring.http_output UTF-8 UTF-8 mbstring.internal_encoding UTF-8 UTF-8 mbstring.language neutral neutral mbstring.strict_detection On Off mbstring.substitute_character no value no value Reproduce code: --------------- Pass a ?x=%FC as a parameter. When followed by other parameters, it is working again. Expected result: ---------------- No hang. Actual result: -------------- Hang (99.9% CPU usage). As a result the script will be aborted later on with "Max execution time exceeded". The first line of PHP Code itself is never called.
