To setthe ini key phar.readonly to 0, from a unix shell script, this is possible on the fly it is possible see below.
The example given on this page has some issues with quoting: (See conversion to simple quotes)
#!/usr/bin/php -d phar.readonly=0
<?php
print(ini_get('phar.readonly')); // Must return 0
// make sure it doesn't exist
@unlink('brandnewphar.phar');
try {
$p = new Phar(dirname(__FILE__) . '/brandnewphar.phar', 0, 'brandnewphar.phar');
} catch (Exception $e) {
echo 'Could not create phar:', $e;
}
echo 'The new phar has ' . $p->count() . " entries\n";
$p->startBuffering();
$p['file.txt'] = 'hi';
$p['file2.txt'] = 'there';
$p['file2.txt']->compress(Phar::GZ);
$p['file3.txt'] = 'babyface';
$p['file3.txt']->setMetadata(42);
$p->setStub('<?php
function __autoload($class)
{
include "phar://myphar.phar/" . str_replace("_", "/", $class) . ".php";
}
Phar::mapPhar("myphar.phar");
include "phar://myphar.phar/startup.php";
__HALT_COMPILER();');
$p->stopBuffering();
// Test
$m = file_get_contents("phar://brandnewphar.phar/file2.txt");
$m = explode("\n",$m);
var_dump($m);
/* Output:

Phar::startBuffering
(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 1.0.0)
Phar::startBuffering — Start buffering Phar write operations, do not modify the Phar object on disk
Descrizione
public Phar::startBuffering(): void
Although technically unnecessary, the Phar::startBuffering() method can provide a significant performance boost when creating or modifying a Phar archive with a large number of files. Ordinarily, every time a file within a Phar archive is created or modified in any way, the entire Phar archive will be recreated with the changes. In this way, the archive will be up-to-date with the activity performed on it.
However, this can be unnecessary when simply creating a new Phar archive, when it would make more sense to write the entire archive out at once. Similarly, it is often necessary to make a series of changes and to ensure that they all are possible before making any changes on disk, similar to the relational database concept of transactions. the Phar::startBuffering()/Phar::stopBuffering() pair of methods is provided for this purpose.
Phar write buffering is per-archive, buffering active for the
foo.phar Phar archive does not affect changes
to the bar.phar Phar archive.
