GlobIterator::__construct

(PHP 5 >= 5.3.0)

GlobIterator::__construct — Construct a directory using glob

说明

public GlobIterator::__construct ( string $path [, int $flags = FilesystemIterator::KEY_AS_PATHNAME | FilesystemIterator::CURRENT_AS_FILEINFO ] )

Constructs a new directory iterator from a glob expression.

参数

path: The path of the directory.
flags: Option flags, the flags may be a bitmask of the FilesystemIterator constants.

范例

Example #1 GlobIterator example

  <?php
$iterator  = new  GlobIterator ( '*.dll' ,  FilesystemIterator :: KEY_AS_FILENAME );

if (! $iterator -> count ()) {
    echo  'No matches' ;
} else {
     $n  =  0 ;

     printf ( "Matched %d item(s)\r\n" ,  $iterator -> count ());

    foreach ( $iterator  as  $item ) {
         printf ( "[%d] %s\r\n" , ++ $n ,  $iterator -> key ());
    }
}
 ?>

以上例程的输出类似于：

Matched 2 item(s)
[1] php5ts.dll
[2] php_gd2.dll

As seen in example above, first parameter in the GlobIterator constructor is not a path but a pattern which listed filenames should match.

GlobIterator doesn??t have a way to support GLOB_BRACE!

<?php $iterator = new GlobIterator(getcwd. '

public __construct ( Iterator $iterator )

public void next ( void )

public IteratorIterator::__construct ( Traversable $iterator )

public mixed IteratorIterator::current ( void )

public Traversable IteratorIterator::getInnerIterator ( void )

public scalar IteratorIterator::key ( void )

public void IteratorIterator::next ( void )

public void IteratorIterator::rewind ( void )

public bool IteratorIterator::valid ( void )

}

InfiniteIterator::__construct — Constructs an InfiniteIterator
InfiniteIterator::next — Moves the inner Iterator forward or rewinds it

It is important to realise that rewind() must be called on any iterator before using it or you may experience undefined behaviour, see example code and output here http://3v4l.org/rvNpU

See this bug report https://bugs.php.net/bug.php?id=63823&edit=2 for a fuller explanation.

to loop through object keys and reset to the start, try this:
<?php $obj = new stdClass(); $obj->Mon = "Monday"; $obj->Tue = "Tuesday"; $obj->Wed = "Wednesday"; $obj->Thu = "Thursday"; $obj->Fri = "Friday"; $obj->Sat = "Saturday"; $obj->Sun = "Sunday"; $infinate = new InfiniteIterator(new ArrayIterator($obj)); foreach ( new LimitIterator($infinate, 0, 14) as $value ) { print($value . PHP_EOL); } ?>

will output:

Monday
Tuesday
Wednesday
Thursday
Friday
Saturday
Sunday
Monday
Tuesday
Wednesday
Thursday
Friday
Saturday
Sunday

Can be useful when doing date operations or recurring events
