Apabila saya cuba menggunakan operator curl dan paip untuk menghantarnya terus ke php untuk melaksanakan pemasangan yang dimuat turun, saya mendapat ralat:

$ curl -s https://getcomposer.org/installer | php
#!/usr/bin/env php
All settings correct for using Composer
Downloading...
The download is corrupt, retrying...
Downloading...
The download is corrupt, retrying...
Downloading...
The download is corrupt (internal corruption of phar "/work/doc/composer.phar" (truncated entry)), aborting.

Kemudian saya memuat turun pemasangan secara manual:

$ curl -s https://getcomposer.org/installer > composer

Kemudian saya mengesan secara manual di mana ralat berlaku, dan kemudian mengesan percubaan...catch statement:

......

try {
            // test the phar validity
            echo $file;
            $phar = new Phar($file);
            // free the variable to unlock the file
            unset($phar);
            break;
        } catch (Exception $e) {
            if (!$e instanceof UnexpectedValueException && !$e instanceof PharException) {
                throw $e;
            }
            unlink($file);
            if ($retries) {
                if (!$quiet) {
                   out('The download is corrupt, retrying...', 'error');
                }
            } else {
                out('The download is corrupt ('.$e->getMessage().'), aborting.', 'error');
                exit(1);
            }
        }
        
......

Ralat berlaku semasa menggunakan Phar baharu, jadi saya mengeluarkan kod ini dan melaksanakannya secara berasingan PHP melaporkan ralat ini:

$ cat test.php 
<?php

$file = '/work/doc/composer.phar';

$phar = new Phar($file);

unset($phar);

Kemudian laksanakan ujian ini.php dan lihat ralat ini:

$ php test.php 
PHP Fatal error:  Uncaught exception 'UnexpectedValueException' with message 'internal corruption of phar "/work/doc/composer.phar" (__HALT_COMPILER(); not found)' in /work/doc/test.php:5
Stack trace:
#0 /work/doc/test.php(5): Phar->__construct('/work/doc/compo...')
#1 {main}
  thrown in /work/doc/test.php on line 5

Tetapi saya sudah mempunyai skrip yang dimuat turun bernama composer.phar Walaupun saya menamakan test.php composer.phar, ia tidak berfungsi. Berikut ialah parameter kompilasi php saya:
