**PHP** (PHP: Hypertext Preprocessor) ni lugha ya scripting ya upande wa server inayotumiwa sana, iliyoundwa kwa kumkusanya kwa **maendeleo ya wavuti**. Nambari ya PHP inaendesha kwenye seva, ikizalisha HTML (au JSON) ambayo inatumwa kwa kivinjari. Inaeneza sehemu kubwa sana ya mtandao. ## Mfano rahisi ```php tags; it can be mixed with HTML $name = "World"; ?>

Hello, !

``` PHP inaweza kuingiza moja kwa moja katika HTML — asili yake kama lugha ya kiolezo — ingawa PHP ya sasa kwa kawaida inawatenganisha mantiki na uwasilishaji. ## Sifa za msingi ```text ✓ Server-side — runs on the web server, produces HTML/JSON for the client ✓ Dynamically typed — no type declarations required (but modern PHP supports them) ✓ Easy to deploy — runs on virtually every web host; simple shared hosting works ✓ Mature ecosystem — Composer (packages), huge community, vast documentation ✓ Modern PHP (8.x) is fast and feature-rich (types, JIT, enums, etc.) ``` ## PHP inatumiwa wapi ```text ✓ Powers a large % of the web — WordPress (~40% of all sites), Drupal, Joomla ✓ Major frameworks: Laravel, Symfony — full-featured modern web apps & APIs ✓ E-commerce (Magento, WooCommerce), CMS platforms ✓ Facebook was built on PHP; widely used for content sites and web back-ends ``` ## PHP ya sasa dhidi ya sifa ya zamani ```text PHP's early reputation (inconsistent, insecure) is outdated. Modern PHP 8.x has: ✓ Strong typing, performance improvements (JIT, OPcache) ✓ Clean OOP, namespaces, Composer, PSR standards ✓ Mature frameworks (Laravel/Symfony) enforcing good practices ``` ## Kwa nini hili lina maana PHP inabaki kuwa mojawapo ya lugha muhimu zaidi za wavuti, inayoeneza sehemu kubwa sana ya mtandao (WordPress peke yake inafanya kazi ~40% ya tovuti zote), kwa hivyo kuelewa ni nini na inatumiwa wapi ni muktadha wa thamani. Nukta za msingi: ni lugha **ya upande wa server** iliyoundwa kwa makusudi kwa wavuti (inazalisha HTML/JSON), ni rahisi kusambaza (inaendesha kwenye mitambo karibu yote), na — muhimu — **PHP ya sasa 8.x imeenea kwa kiasi kikubwa** zaidi ya sifa yake ya zamani, ikikubaliana na kuandika kwa nguvu, utendaji (JIT/OPcache), OOP safi, Composer, na mifumo ingavu (Laravel, Symfony) inayotumia mbinu za kitaaluma. Kutambua kueneza kwa PHP, muundo wake wa kwanza wa wavuti, na kwamba PHP ya sasa ni lugha yenye uwezo, mwenye zana nzuri inabweka muhtasari wa kila kitu kingine juu ya kufanya kazi nayo.
