APC Cache Considerations for Virtual Hosting Environments

APC cache does not work well in a virtual hosting environment unless PHP is running as FCGID, and every individual virtual host has a unique PHP.ini and a unique fcgiwrapper. This is not the case with many virtual hosting environments because the memory and CPU requirements are too great.

Auto Mailer Form with Validation and reCAPTCHA

…Form Builder Class, was recently refactored with Bootstrap, and it also supports validation and reCAPTCHA. PFBC does not include a form handler, but it does take the difficult and redundant work out of creating self-validating forms. Adding an auto-mailer to PFBC is very simple, however. You just need a simple PHP if/else and all is well. If you have read this far, you should go ahead and download PFBC version 3 (with Bootstrap). You’ll wa… 1, 0, 0, 0 and 778.35
