Fixing “Call to undefined function proc_open()” Error in Laravel Application

Project Overview: Our Laravel application (PHP 8.1.31, Laravel 8.83.27) is encountering the following error when attempting to send emails: Call to undefined function proc_open() This error occurs in the SwiftMailer library when it attempts to use proc_open() (typically for the sendmail transport). The likely causes are either: The proc_open() function is disabled in our PHP configuration ([login to view URL]) via the disabled_functions directive, or The current mailing setup (sendmail) isn’t supported in our hosting environment. Scope of Work: Diagnosis & Analysis: Examine the PHP configuration ([login to view URL]) to see if proc_open() is disabled. Assess the hosting environment for any restrictions related to process control functions. Review the current Laravel mail configuration to confirm if we’re using sendmail or another transport. Recommendations & Implementation: Option A: Enable proc_open() by updating the PHP configuration, if security policies and hosting allow. Option B: Switch the mail transport method from sendmail to SMTP (or another supported method) by updating the Laravel configuration (e.g., the .env file). Implement the chosen solution and test the email sending functionality. Testing & Documentation: Thoroughly test the fix to ensure email functionality works as expected. Provide documentation detailing the changes made and recommendations for future maintenance. Deliverables: A diagnostic report outlining the root cause of the error. Implementation of the chosen solution (either re-enabling proc_open() or switching to SMTP). Updated PHP and/or Laravel mail configuration files. Documentation of all changes and testing results. Candidate Qualifications: Strong experience with PHP (especially PHP 8.x) and the Laravel framework. Familiarity with SwiftMailer and Laravel’s mailing system. Experience in server configuration and managing [login to view URL] settings. Ability to provide clear documentation and troubleshoot server-related issues. Timeline & Budget: Timeline: We expect the project to be completed within 1–2 weeks. Budget: We are budgeting approximately $300–$600, based on an estimated 3–6 hours of work. The final cost may vary depending on the scope and any additional requirements.
