Phar::setStub — Used to set the PHP loader or bootstrap stub of a Phar archive
$stub
[, int $len
= -1
] )Note:
此方法需要 将 php.ini 中的 phar.readonly 设为 0 以适合 Phar 对象. 否则, 将抛出PharException.
This method is used to add a PHP bootstrap loader stub to a new Phar archive, or to replace the loader stub in an existing Phar archive.
The loader stub for a Phar archive is used whenever an archive is included directly as in this example:
<?php
include 'myphar.phar' ;
?>
The loader is not accessed when including a file through the phar stream wrapper like so:
<?php
include 'phar://myphar.phar/somefile.php' ;
?>
stub
A string or an open stream handle to use as the executable stub for this phar archive.
len
成功时返回 TRUE
, 或者在失败时返回 FALSE
。
UnexpectedValueException is thrown if phar.readonly is enabled in php.ini. PharException is thrown if any problems are encountered flushing changes to disk.
Example #1 A Phar::setStub() example
<?php
try {
$p = new Phar ( dirname ( __FILE__ ) . '/brandnewphar.phar' , 0 , 'brandnewphar.phar' );
$p [ 'a.php' ] = '<?php var_dump("Hello");' ;
$p -> setStub ( '<?php var_dump("First"); Phar::mapPhar("brandnewphar.phar"); __HALT_COMPILER(); ?>' );
include 'phar://brandnewphar.phar/a.php' ;
var_dump ( $p -> getStub ());
$p [ 'b.php' ] = '<?php var_dump("World");' ;
$p -> setStub ( '<?php var_dump("Second"); Phar::mapPhar("brandnewphar.phar"); __HALT_COMPILER(); ?>' );
include 'phar://brandnewphar.phar/b.php' ;
var_dump ( $p -> getStub ());
} catch ( Exception $e ) {
echo 'Write operations failed on brandnewphar.phar: ' , $e ;
}
?>
以上例程会输出:
string(5) "Hello" string(82) "<?php var_dump("First"); Phar::mapPhar("brandnewphar.phar"); __HALT_COMPILER(); ?>" string(5) "World" string(83) "<?php var_dump("Second"); Phar::mapPhar("brandnewphar.phar"); __HALT_COMPILER(); ?>"

If your stub has a namespace, it is used for each include that doesn't define one.

One thing I had alot of problems with, is that i can't set the stub unless I put the whole operation inside of a try/catch block!
If i remove the try/catch block it will error our and not write the stub with the content i want it to have.
