Phar::offsetGet — Gets a PharFileInfo object for a specific file
$offset
)This is an implementation of the ArrayAccess interface allowing direct manipulation of the contents of a Phar archive using array access brackets. Phar::offsetGet() is used for retrieving files from a Phar archive.
offset
The filename (relative path) to look for in a Phar.
A PharFileInfo object is returned that can be used to iterate over a file's contents or to retrieve information about the current file.
This method throws BadMethodCallException if the file does not exist in the Phar archive.
Example #1 Phar::offsetGet() example
As with all classes that implement the ArrayAccess interface, Phar::offsetGet() is automatically called when using the [] angle bracket operator.
<?php
$p = new Phar ( dirname ( __FILE__ ) . '/myphar.phar' , 0 , 'myphar.phar' );
$p [ 'exists.txt' ] = "file exists\n" ;
try {
// automatically calls offsetGet()
echo $p [ 'exists.txt' ];
echo $p [ 'doesnotexist.txt' ];
} catch ( BadMethodCallException $e ) {
echo $e ;
}
?>
以上例程会输出:
file exists Entry doesnotexist.txt does not exist
