Sequential execution of php exec commands?

Question

PHP

Colleagues, welcome!

I set up continuous deployment for testing in production

It is known that && logical AND
The second command will be executed if the first one completed without errors.

But the problem is that a number of commands give errors, but at the same time it completes successfully.
For example:

/usr/local/bin/docker-compose -f docker-compose-epsyteam.yml exec app composer install

It may end with ErrorCode > 0
But this does not mean that you do not need to continue to execute commands.

Further commands are not executed.

I tried to execute each command in a loop, but exec () does not wait.

<?php

define('GITHUB_SECRET', '***********');

set_time_limit(3600);
header('Content-Type', 'text/plain');

// Ensure signature exists
if (!isset($_SERVER['HTTP_X_HUB_SIGNATURE'])) {
  http_response_code(403);
  die('Missing signature');
}

// Ensure that signature is formed as expected
$signature = explode('=', $_SERVER['HTTP_X_HUB_SIGNATURE']);
if (2 !== count($signature)) {
  http_response_code(400);
  die('Malformed signature');
}

// Parse signature
$algos = hash_algos();
list($algo, $hash) = $signature;
if (!in_array($algo, $algos)) {
  http_response_code(400);
  die("Unknown hashing algo: $algo");
}

// Load payload
$payload = file_get_contents('php://input');

// Check signature
$expectedHash = hash_hmac($algo, $payload, GITHUB_SECRET);
if ($expectedHash !== $hash) {
  http_response_code(403);
  die('Invalid signature');
}


// Parse data
$data = json_decode($payload, true);
       
// Configure commands
$commands = [
  "epsy-me/epsy-api" => [
    "cd /var/www/epsyteam/data/epsy-api/",
    "pwd", 
    "git reset --hard",
    "git pull origin develop",
    "/usr/local/bin/docker-compose -f docker-compose-epsyteam.yml kill",
    "/usr/local/bin/docker-compose -f docker-compose-epsyteam.yml down",
    "/usr/local/bin/docker-compose -f docker-compose-epsyteam.yml up -d --build",
    "/usr/local/bin/docker-compose -f docker-compose-epsyteam.yml exec app composer install",
    "/usr/local/bin/docker-compose -f docker-compose-epsyteam.yml exec app composer dump-env prod",
    "/usr/local/bin/docker-compose -f docker-compose-epsyteam.yml exec app php bin/console doctrine:schema:update --dump-sql --force"
  ]
];




// Run
$repo = $data['repository']['full_name'];
if (isset($commands[$repo])) {
    $command = implode(' && ', $commands[$repo]);
  
  $output = [];
  $output[] = $repo;
  $output[] = "================================================";
  exec($command, $output, $returnCode);
  
  mailTo("[email protected]", implode("\n - ", $output), "EPSY DEPLOYMENT");
  
} else {
  http_response_code(400);
  $message = "Repository not configured: $repo\n";
  mailTo("[email protected]", $message, "EPSY DEPLOYMENT ERROR");
  die($message);
}



function mailTo($to, $message, $subject) 
{
  $headers = "From: [email protected]" . "\r\n" .
        'X-Mailer: PHP/' . phpversion();
  mail($to, $subject, $message, $headers);
}

Answer 1

# man bash
...
Commands separated by a ; are executed sequentially; the shell waits for each command
to terminate in turn.

Answer 2

but exec() doesn't wait

Waiting.
