I hope you're doing well. I'm relatively new to PHP and I've been struggling with some issues regarding email handling and SMTP connections. I've been working on a web project that requires me to send emails using PHP, but I keep encountering errors. I'm hoping someone here can help me troubleshoot them.
To provide some context, I have a form on my website where users can submit their information. Upon submission, I want to send an email to notify the site administrators. Here are the specific issues I'm facing:
1. Email not being sent: When a user submits the form, the code executes without any errors, but the email never gets sent. I have double-checked the email addresses and they are correct. I'm using the `mail()` function in PHP to send the email.
2. SMTP connection issues: I've read that using an SMTP server is a better option for sending emails than relying on the server's built-in `mail()` function. However, when I attempt to establish an SMTP connection using PHP, I encounter errors. I have the correct credentials and have ensured that ports are open, but still no luck.
Now, I'd like to ask for your help with troubleshooting these issues. What are some common causes of errors in PHP email handling or SMTP connections? And how can I go about solving them?
I would really appreciate any guidance or suggestions you can provide. Thank you in advance for your help!
