VMWare Server Console allows you to connect to a VMWare Server virtual machine running either on your local machine or a remote machine. The remote machine might be on your local network or located somewhere on the Internet. This post looks at how to deal with the error message in the VMWare Server Console "unable to connect to remote host: cannot connect to remote host x.y.z.a: connection refused" when trying to connect.
APC is the Alternative PHP Cache, which is a free, open, and robust framework for caching and optimizing PHP intermediate code. I posted about how to install APC on Linux a couple of days ago, and will now look at the apc.php script which comes with APC and shows information about how much of the cache is being used, what files are being cached, the number of times they’ve been accessed etc.
I needed to install the MSSQL libraries for PHP on a CentOS 5 server and ran into a few issues when installing some of the required dependencies, getting "Transaction Check Error" error messages which indicated conflicts between files in packages.
APC is the Alternative PHP Cache, which is a free, open, and robust framework for caching and optimizing PHP intermediate code. What this means is that APC reads your PHP files, parses them into a more efficient binary format and then caches them in memory so that each request for your PHP files and PHP library files can be fed from the parsed cache. This will generally lead to a speed increase when serving a PHP site, especially one with a lot of library files. This post looks at how to install APC for PHP on Linux. The Linux distribution I used was CentOS 5, but it should be fairly similar for most distros.
An ISO image or .iso file contains the disk image of an ISO 9660 file system, which is used for storing data on CD-ROMs and DVD-ROMs. It is possible to take an ISO image and record it onto a CD or DVD using various applications for doing so, and it is also possible to mount the ISO image using Linux, so that you can access the files without having to actually burn it to disk first.
If you get the following error message in PHP then it means you need to have the PHP GD extension installed. Obviously the /path/to/file.php will be the actual path and filename of the PHP script the error occured in, and the line number will be the actual line.
Fatal error: Call to undefined function ImageCreateFromPNG() in /path/to/file.php on line 379
You’ll also get this error message using other functions such as ImageCreateFromJPEG() if the PHP GD library is not installed.
