Phar::isValidPharFilename — Returns whether the given filename is a valid phar filename

说明

final public static Phar::isValidPharFilename ( string $filename [, bool $executable = TRUE ] ) : bool

Returns whether the given filename is a valid phar filename that will be recognized as a phar archive by the phar extension. This can be used to test a name without having to instantiate a phar archive and catch the inevitable Exception that will be thrown if an invalid name is specified.

参数

filename: The name or full path to a phar archive not yet created
executable: This parameter determines whether the filename should be treated as a phar executable archive, or a data non-executable archive

返回值

Returns TRUE if the filename is valid, FALSE if not.
