Here is a very simple program for creating phar files with CLI. Note that it requires phar.readonly in php.ini set to false (Off).
<?php
$filename = "default";
$dir = "./";
$regex = "/^(?!.*build\\.php)(?:.*)$/";
$main = "main.php";
$shebang = "#!/usr/bin/env php";
$chmod = true;
for ($i = 0; $i < $argc; $i++) {
switch ($argv[$i]) {
case "-o":
$i++;
if ($i >= $argc) {
echo "Missing output file name" . PHP_EOL;
exit(1);
}
$filename = $argv[$i];
break;
case "-i":
$i++;
if ($i >= $argc) {
echo "Missing input directory name" . PHP_EOL;
exit(1);
}
$dir = $argv[$i];
break;
case "-p":
$i++;
if ($i >= $argc) {
echo "Missing regular expression pattern" . PHP_EOL;
exit(1);
}
$regex = $argv[$i];
break;
case "-m":
$i++;
if ($i >= $argc) {
echo "Missing main file" . PHP_EOL;
exit(1);
}
$main = $argv[$i];
break;
case "-b":
$i++;
if ($i >= $argc) {
echo "Missing shebang of file" . PHP_EOL;
exit(1);
}
$shebang = $argv[$i];
break;
case "--no-chmod":
$chmod = false;
break;
}
}
if (file_exists($filename)) unlink($filename);
$phar = new Phar($filename);
$phar->buildFromDirectory($dir, $regex);
$phar->setStub(($shebang ? $shebang . PHP_EOL : "") . $phar->createDefaultStub($main));
if ($chmod) {
chmod($filename, fileperms($phar) | 0700);
}
