PHP Contact Manager

This is a simple command-line Contact Manager application written in PHP. It allows you to manage a list of contacts, including their names, email addresses, and phone numbers, stored in either JSON or CSV format.

Features

• Add new contacts with a name, email, and phone number.
• List all saved contacts with their details.
• Search contacts by name.
• Delete contacts by index.
• Supports data storage in either JSON or CSV format.

Requirements

• PHP 7.4 or higher

Setup

1. Clone this repository or download the PHP script and place it in a directory on your system.

2. Create a file named test.json (or test.csv if you prefer CSV) in the same directory.

   • You can start with an empty file ([] for JSON or no content for CSV), or use sample data like below:

   Sample test.json:

   [
       {
           "name": "Alice Johnson",
           "email": "alice.johnson@example.com",
           "phone": "555-1234"
       },
       {
           "name": "Bob Smith",
           "email": "bob.smith@example.com",
           "phone": "555-5678"
       }
   ]
   
   

Here’s a README.md for your Contact Manager project:
