Finder

class Finder implements IteratorAggregate, Countable

Finder allows to build rules to find files and directories.

It is a thin wrapper around several specialized iterator classes.

All rules may be invoked several times.

All methods return the current Finder object to allow easy chaining:

$finder = Finder::create()->files()->name('*.php')->in(DIR);

IGNORE_VCS_FILES
IGNORE_DOT_FILES

$this sort(Closure $closure)

Sorts files and directories by an anonymous function.

The anonymous function receives two \SplFileInfo instances to compare.

This can be slow as all the matching files and directories must be retrieved for comparison.

Parameters

Closure $closure An anonymous function

Return Value

$this

See also

SortableIterator

$this sortByName()

Sorts files and directories by name.

This can be slow as all the matching files and directories must be retrieved for comparison.

Return Value

$this

See also

SortableIterator

$this sortByType()

Sorts files and directories by type (directories before files), then by name.

This can be slow as all the matching files and directories must be retrieved for comparison.

Return Value

$this

See also

SortableIterator

$this sortByAccessedTime()

Sorts files and directories by the last accessed time.

This is the time that the file was last accessed, read or written to.

This can be slow as all the matching files and directories must be retrieved for comparison.

Return Value

$this

See also

SortableIterator

$this sortByChangedTime()

Sorts files and directories by the last inode changed time.

This is the time that the inode information was last modified (permissions, owner, group or other metadata).

On Windows, since inode is not available, changed time is actually the file creation time.

This can be slow as all the matching files and directories must be retrieved for comparison.

Return Value

$this

See also

SortableIterator

$this sortByModifiedTime()

Sorts files and directories by the last modified time.

This is the last time the actual contents of the file were last modified.

This can be slow as all the matching files and directories must be retrieved for comparison.

Return Value

$this

See also

SortableIterator

$this filter(Closure $closure)

Filters the iterator with an anonymous function.

The anonymous function receives a \SplFileInfo and must return false to remove files.

Parameters

Closure $closure An anonymous function

Return Value

$this

See also

CustomFilterIterator

Forces the following of symlinks.

Return Value

$this

$this ignoreUnreadableDirs(bool $ignore = true)

Tells finder to ignore unreadable directories.

By default, scanning unreadable directories content throws an AccessDeniedException.

Parameters

bool $ignore

Return Value

$this

$this in(string|array $dirs)

Searches files and directories which match defined rules.

Parameters

string|array $dirs A directory path or an array of directories

Iterator|SplFileInfo[] getIterator()

Returns an Iterator for the current Finder configuration.

This method implements the IteratorAggregate interface.

LogicException if the in() method has not been called

$this append(mixed $iterator)

Appends an existing set of files/directories to the finder.

The set can be another Finder, an Iterator, an IteratorAggregate, or even a plain array.

Parameters

mixed $iterator
