This makes PHP ideally suited for server-side programming and creating dynamic websites.
One of PHP's biggest advantages is its tight integration with HTML and databases. PHP code can be directly embedded into HTML documents using tags, avoiding the need for templating frameworks required by other languages like Python and Ruby. This simplicity of mixing HTML and PHP code makes PHP a straightforward language for beginners to pick up.
PHP also has robust built-in features for interacting with SQL databases like MySQL, PostgreSQL, and others. Database queries and operations are handled seamlessly in PHP without requiring additional libraries. This integration with MySQL in particular led to the popularity of the LAMP (Linux, Apache, MySQL, PHP) stack for web development. The LAMP stack remains a common, open source platform for building web applications thanks to PHP handling all the back-end server-side processing and database logic.
Beyond just websites, PHP powers many widely used web applications as well. Content management systems like WordPress and Drupal are built with PHP. Ecommerce platforms including Magento and shopping carts rely on PHP for the backend. Frameworks like Laravel provide structures for quickly building custom web apps using PHP. The language's maturity, ecosystem of tools, and huge open source community make PHP well-suited for full-stack web application development.

The contract should also address confidentiality through non-disclosure agreements (NDAs). This prevents the developer from sharing any sensitive information about your business or project. Intellectual property rights are another key area - the contract should specify who owns any code or assets produced. You'll generally want to retain IP rights as the hiring party.
Adhering to applicable laws and regulations is part of drafting a sound contract. Elements like anti-discrimination clauses, arbitration agreements, and liability limitations can be included. For international engagements, consider both parties' jurisdictions. Consulting a lawyer can be worthwhile to ensure proper legal obligations are covered in the hiring contract and avoid any compliance issues down the line.
Intellectual Property Considerations
Intellectual property becomes crucial when hiring a freelance developer. The ownership of any code, scripts, documentation or digital assets produced should be clearly delineated in the contract. This avoids potential disputes later on.
Oftentimes, the hiring party retains full IP rights to anything produced by a contractor or freelancer under a "work for hire" arrangement. However, you can also grant the developer certain licensing rights, for example allowing them to reuse portions of the code in future projects. Get legal advice about the best IP approach for your specific project and jurisdiction.
Non-disclosure agreements (NDAs) are another way to protect IP and confidential information. NDAs prohibit the developer from sharing or using any proprietary details they gain access to through their work. This provides protection even if you don't retain full IP rights. Make sure to specify any exclusions like open source libraries used.
Handling intellectual property properly from the outset prevents headaches both during and after the project. Consult an attorney to craft suitable IP ownership and NDA terms in your hiring contract.
