First thing in the morning, I got this mysql server error. ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) Apparently, /tmp/mysql.sock is missing. I know that’s the right path, but the file is not there. I restarted the mysql server by press the “Start MySQL Server” button, but it’s not running. I ran mysqld, but it gave me more errors and failed to start. I ended up making it work by providing a my.cnf file, which I hadn’t needed. ...
Math problems are getting much trickier nowadays…
Very often, when data size gets bigger and bigger, some scripts will break due to default memory limit. I got the following error today. Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 72 bytes) in /someDir/myScript.php on line 15 Segmentation fault: 11 I checked my php help. I am using version 5.3.6. $ php -h Usage: php [options] [-f] [--] [args...] php [options] -r [--] [args...] php [options] [-B ] -R [-E ] [--] [args...] php [options] [-B ] -F [-E ] [--] [args...] php [options] -- [args...] php [options] -a -a Run as interactive shell -c | Look for php.ini file in this directory -n No php.ini file will be used -d foo[=bar] Define INI entry foo with value 'bar' -e Generate extended information for debugger/profiler -f Parse and execute . -h This help -i PHP information -l Syntax check only (lint) -m Show compiled in modules -r Run PHP without using script tags -B Run PHP before processing input lines -R Run PHP for every input line -F Parse and execute for every input line -E Run PHP after processing all input lines -H Hide any passed arguments from external tools. -s Output HTML syntax highlighted source. -v Version number -w Output source with stripped comments and whitespace. -z Load Zend extension . args...

Looks like -d with do it. So I ran the following: php -d memory_limit=512M myScript.php It worked fine. If you can afford to change your php.ini file, use - -ini to see where your php.ini file is, then make your changes accordingly. You can also use -n to ignore your php.ini file, but then you will be using default parameters which may be even harder to debug. ...

Below is how you can detect non-ascii characters with javascript. s = $("#something").val(); for (var i=0; n = 128) { alert('Invalid character '' + String.fromCharCode(c) + '''); return false; // or throw an error } } Of course if you have to take in non-ascii values, then be prepared to set up your environments first.
