Introduction to PHP in Sinhala - Lesson 01
PHP කියන්නේ මොකක්ද?
- PHP කියන්නේ "Hypertext Preprocessor" කියන එකට.
- ආරම්භයේදී PHP අර්ථ දැක්වුයේ "Personal Home Page Tools" ලෙස.
- PHP යනු පුළුල් වශයෙන් භාවිතා වෙන open source (විවුර්ත කේත) scripting language එකක්.
- PHP scripts execute වන්නේ server එකක් තුල පමණයි.
- PHP නොමිලේ download කරගැනීමට සහ භාවිතා කිරීමට පුළුවන්.
PHP File එකක් කියන්නේ මොකක්ද?
- PHP files එකක text, HTML, CSS, JavaScript, සහ PHP code ඇතුලත් කල හැකියි.
- PHP code එක server එක තුල execute වෙලා result එක අපේ web browser එක තුල HTML පිටුවක් ආකාරයට පෙන්නනවා.
- PHP file එකේ extension එක තමයි "
.php"
PHP වලින් මොනවද කරන්න පුළුවන්?
- PHP වලට පුළුවන් generate කරන්න dynamic page content. (ඒ කියන්නේ මේ kuppiya.lk වගේ ඔයාල කරන දේවල් අනුව පේජ් එක වෙනස් වෙනවා. ඔයා profile picture එකක් upload කලොත් ඒක ඒ අවස්ථාවෙම පෙන්නනවා. code edit කර කර photos දාන්න ඕනේ නැහැ.)
- PHP වලට පුළුවන් server එක තුල files create කරන්න, files open කරන්න, read කරන්න, write කරන්න, delete කරන්න, සහ close කරන්න.
- PHP වලට පුළුවන් form එකක data එකතු කරගන්න. (ඔයාල kuppiya.lk එකේ register වෙනකොට type කරපු data එකතු කරලා database එකට යවනව වගේ.)
- PHP මගින් cookies සෙන්ඩ් කරන්න සහ receive කරන්න පුළුවන්.
- PHP මගින් පුළුවන් database එකකට data add කරන්න, delete කරන්න හා modify කරන්න.
- PHP යොදාගෙන පුළුවන් data encrypt (ඛේතනය) කරන්න.
Next Lesson එකෙන් කියල දෙන්නම් PHP code එකක් run කරගැනීම සදහා පරිගණකය සකසාගතයුතු ආකාරය.

ගොඩක් අය php වලින් individual project කරන නිසා මේක ගොඩක් වැදගත් වෙයි 👍️
@Kelum_Priyankara බොහොම ස්තුතියි.
