PHPSPL standard library file operations (SplFileInfo and SplFileObject) instance, _ PHP Tutorial

PHPSPL standard library file operations (SplFileInfo and SplFileObject) instance ,. For file operations (SplFileInfo and SplFileObject) instances in the PHPSPL standard library, PHPSPL provides the SplFileInfo and SplFileObject classes to process file operations. SplFileInfo is used to obtain details about file operations (SplFileInfo and SplFileObject) instances in the php spl standard library,

Php spl provides SplFileInfo and SplFileObject classes to process file operations.

SplFileInfo is used to obtain file details:

The code is as follows:
$ File = new SplFileInfo('foo-bar.txt ');

Print_r (array (
'Getatime' => $ file-> getATime (), // last access time
'Getbasename' => $ file-> getBasename (), // Obtain the basename without a path
'Getctime' => $ file-> getCTime (), // Get the inode modification time
'Getextension' => $ file-> getExtension (), // file extension
'Getfilename' => $ file-> getFilename (), // get the file name
'Getgroup' => $ file-> getGroup (), // Get a file Group
'Getinode' => $ file-> getInode (), // get the file inode
'Getlinktarget' => $ file-> getLinkTarget (), // Obtain the target file of the file link
'Getmtime' => $ file-> getMTime (), // get the last modification time
'Getowner' => $ file-> getOwner (), // file owner
'Getpath' => $ file-> getPath (), // file path without a file name
'Getpathinfo' => $ file-> getPathInfo (), // The SplFileInfo object of the parent path
'Getpathname' => $ file-> getPathname (), // full path
'Getperms' => $ file-> getPerms (), // file permission
'Getrealpath' => $ file-> getRealPath (), // absolute file path
'Getsize' => $ file-> getSize (), // file size, in bytes
'Gettype' => $ file-> getType (), // file dir link
'Isdir' => $ file-> isDir (), // whether it is a directory
'Isfile' => $ file-> isFile (), // whether it is a file
'Islink' => $ file-> isLink (), // whether it is a shortcut
'Isexecutable' => $ file-> isExecutable (), // whether it is executable
'Isreadable' => $ file-> isReadable (), // whether it is readable
'Iswritable' => $ file-> isWritable (), // whether to write
));

SplFileObject inherits SplFileInfo and implements RecursiveIterator and SeekableIterator interfaces for file traversal, searching, and operations.

Traversal:
The code is as follows:
Try {
Foreach (new SplFileObject('foo-bar.txt ') as $ line ){
Echo $ line;
}
} Catch (Exception $ e ){
Echo $ e-> getMessage ();
}

Find the specified row:
The code is as follows:
Try {
$ File = new SplFileObject('foo-bar.txt ');
$ File-> seek (2 );
Echo $ file-> current ();
} Catch (Exception $ e ){
Echo $ e-> getMessage ();
}

Write a csv file:
The code is as follows:
$ List = array (
Array ('AAA', 'BBB ', 'CCC', 'ddddd '),
Array ('20140901', '20160901', '20160901 '),
Array ('"aaa"', '"bbb "')
);

$ File = new SplFileObject ('file.csv ', 'w ');

Foreach ($ list as $ fields ){
$ File-> fputcsv ($ fields );
}
