This extension is
EXPERIMENTAL. The behaviour of this extension --
including the names of its functions and anything else documented
about this extension -- may change without notice in a future release of PHP.
Use this extension at your own risk.
The functions in this module try to guess the content type
and encoding of a file by looking for certain
magic byte sequences at specific
positions within the file. While this is not a bullet proof
approach the heuristics used do a very good job.
magic_open library is needed to build this extension.
A short installation note: just type
in your console.
This extension has no configuration directives defined in php.ini.
There is one resource used in Fileinfo extension: a magic database
descriptor returned by finfo_open().
The constants below are defined by this extension, and
will only be available when the extension has either
been compiled into PHP or dynamically loaded at runtime.
No special handling.
Return a mime string, instead of a textual description.
Decompress compressed files.
Look at the contents of blocks or character special devices.
Return all matches, not just the first.
If possible preserve the original access time.
Don't translate unprintable characters to a \ooo octal
