Class: ezcSystemInfo
|
Provides access to common system variables. [
source]
Variables that not available from PHP directly are fetched using readers specific for each supported system. óorresponding reader automatically detected, attached and forced to scan system info during initialisation. Exception throws if reader can't scan sistem info.
Available readers are:
Readers for otner systems could be added by implementing the
ezcSystemInfoReader interface.
The ezcSystemInfo class has the following properties:
Reader independent, these properties are availiable 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 indicates if the script executed over the web or the shell/command line.
Reader dependent, these properties are not availiable if reader was not intnialized and didn't scan OS:
- Integer cpuCount amount 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";
