Variables not available from PHP directly are fetched using readers specific for each supported system. Corresponding reader is automatically detected, attached and forced to scan system info during initialization. An exception is thrown if the reader can't scan the system info.

Available readers are:

• ezcSystemInfoLinuxReader reader
• ezcSystemInfoMacReader reader
• ezcSystemInfoFreeBsdReader reader
• ezcSystemInfoWindowsReader reader

Readers for other systems can be added by implementing the ezcSystemInfoReader interface.

The ezcSystemInfo class has the following properties:

Reader independent, these properties are available even if system reader was not initialized.

• String osType, OS type (e.g 'unix') or null.
• String osName, OS name (e.g 'Linux') or null.
• String fileSystemType, filesystem type (e.g 'linux') or null.
• String lineSeparator, which is used for line separators on the current OS.
• String backupFileName, backup filename for this platform, '.bak' for win32 and '~' for unix and mac.
• Array phpVersion, with PHP version (e.g. array(5,1,1) ).
• ezcSystemInfoAccelerator phpAccelerator, structure with PHP accelerator info or null ezcSystemInfoAccelerator.
• Bool isShellExecution, flag which indicates if the script was executed over the web or the shell/command line.

Reader dependent, these properties are not available if reader was not initialized and didn't scan OS:

• Integer cpuCount number of CPUs in system or null.
• String cpuType CPU type string (e.g 'AMD Sempron(tm) Processor 3000+') or null.
• Float cpuSpeed CPU speed as float (e.g 1808.743) or null.
• Integer memorySize Memory Size in bytes int (e.g. 528424960) or null.

Example:

1.   $info = ezcSystemInfo::getInstance();
2.   echo 'Processors: ', $info->cpuCount, "\n";
3.   echo 'CPU Type: ', $info->cpuType, "\n";
4.   echo 'CPU Speed: ', $info->cpuSpeed, "\n";

Returns the single instance of the ezcSystemInfo class.

Determines if the script was executed over the web or the shell/command line.

Detects if a PHP accelerator is running and what type it is.

Returns the PHP version as an array with the version elements.
