Class: System

boolean &cat( string $args)

Concatenate files

Usage: 1) $var = System::cat('sample.txt test.txt'); 2) System::cat('sample.txt test.txt > final.txt'); 3) System::cat('sample.txt test.txt >> final.txt');

Note: as the class use fopen, urls should work also

Parameters:

array find( mixed $args)

The "find" command

Usage:

System::find($dir); System::find("$dir -type d"); System::find("$dir -type f"); System::find("$dir -name *.php"); System::find("$dir -name *.php -name *.htm*"); System::find("$dir -maxdepth 1");

Params implemented: $dir -> Start the search at this directory -type d -> return only directories -type f -> return only files -maxdepth <n> -> max depth of recursion -name <pattern> -> search pattern (bash style). Multiple -name param allowed

Parameters:

bool mkDir( string $args)

Make directories.

The -p option will create parent directories

Parameters:

mixed mktemp( [string $args = null])

Creates temporary files or directories. This function will remove the created files when the scripts finish its execution.

Usage: 1) $tempfile = System::mktemp("prefix"); 2) $tempdir = System::mktemp("-d prefix"); 3) $tempfile = System::mktemp(); 4) $tempfile = System::mktemp("-t /var/tmp prefix");

prefix -> The string that will be prepended to the temp name (defaults to "tmp"). -d -> A temporary dir will be created instead of a file. -t -> The target dir where the temporary (file|dir) will be created. If this param is missing by default the env vars TMP on Windows or TMPDIR in Unix will be used. If these vars are also missing c:\windows\temp or /tmp will be used.

Parameters:

bool raiseError( mixed $error)

Output errors with PHP trigger_error(). You can silence the errors with prefixing a "@" sign to the function call: @System::mkdir(..);

Parameters:

mixed rm( string $args)

The rm command for removing files.

Supports multiple files and dirs and also recursive deletes

Parameters:

string tmpdir( )

Get the path of the temporal directory set in the system by looking in its environments variables.

Note: php.ini-recommended removes the "E" from the variables_order setting, making unavaible the $_ENV array, that s why we do tests with _ENV

mixed which( string $program, [mixed $fallback = false])

The "which" command (show the full path of a command)

Parameters:

array _dirToStruct( string $sPath, integer $maxinst, [integer $aktinst = 0], [bool $silent = false])

Creates a nested array representing the structure of a directory

System::_dirToStruct('dir1', 0) => Array ( [dirs] => Array ( [0] => dir1 )

[files] => Array ( [0] => dir1/file2 [1] => dir1/file3 ) )

Parameters:

array _multipleToStruct( array $files)

Creates a nested array representing the structure of a directory and files

Parameters:

array _parseArgs( string $argv, string $short_options, [string $long_options = null])

returns the commandline arguments of a function

Parameters:

void _removeTmpFiles( )

Remove temporary files created my mkTemp. This function is executed

at script shutdown time
