Assalomu alaykum do'slar forumda adashmasam parser,grabber yaratish haqidagi mavzular yo'q shu mavzuda parser va grabber yaratishni o'rganamiz.
birinchi bo'lib o'zim bilgan oddiy grabber yaratishni ko'rsatib bersam

<?php
#### grablanayotgan sayt manzili, sahifasi 
$uzg = file_get_contents('http://site.uz'.$_SERVER['QUERY_STRING']); 
echo $uzg;
?>

shu eng oddiy grabber
qirqishlar, o'zgartirishlarsiz

Grabberni asosini tashkil etuvchi funksiya bu

<?php file_get_contents();
?>

3 kun 4 soat 45 daqiqa 43 soniyadan keyin yozdi:
grabber parserchilar bormi marhamat bilimlarizni o'rtoqlashing
3 kun 10 soat 7 daqiqa 34 soniyadan keyin yozdi:
oddiy grabberlarning eng sodda 3ta funksiyasi:

<?php
#1
$uzg = file_get_contents('sayt.uz'.$_SERVER['QUERY_STRING']); /// grabberning asosiy ishlash funksiyasi grablayotgan saytingizni sizni saytingizda ochib beradi
#2
preg_match(|'olib tashlanadigan qism boshi'(.*?)'oxiri'|is,'olib tashlangan qism orniga yoziladi',$uzg); //regulyarniy virojeniya funksiyasi deyiladi
#3
str_replace(search,replace,subject);
//subject -- manba yani $uzg ga tenglab olgan qism
//search --$uzg dan qidirilayotgan qism
//replace-- searchga yozilgan so'zni o'rniga qo'yiluvchi belgi yoki so'z
?>

3 kun 10 soat 21 daqiqa 47 soniyadan keyin yozdi:
grabber yasash funksiyalari saytni ctrl+u qilib korilgandagi yani saytni skaner qilib korilgandagi html,css,js kodlari bilan ishlaydi menimcha ko'pchilikka yangi o'rganayotganlarga qirqib olish o'rniga qo'yish qiyin tuyulsa kerak chunki o'zimham qirqib olishni yaqindagina o'rgadim va sizlarga ham o'rgatishni istadim
3 kun 10 soat 37 daqiqa 18 soniyadan keyin yozdi:
sizlarga bitta sodda grabber yasab ko'rsatsam qirqib olishni tushunib olishingiz uchun

masalan siz falonchi.uz saytini skanerlab olsangiz, yoki kompda bolsangiz osha saytga kirib ctrl+u qilishning ozi kifoya sizga saytning ochiq kodlarini chiqarib beradi

masalan siz grablayotgan saytni skaner qilinganda quyidagicha kodlar chiqdi deylik

aytaylik sizga faqat h1 teglari ichidagi va p tegi orasidagi sozlar saytingizda chiqishini hohlaysiz demak qolgan qismini kesib tashlay kerak bu preg_match() funksiyasi orqali qilinadi

demak yuqoridagi skannerlangan kodlardan keraksizlarini qirqib tashlayman

<?php
//birinchi yuqori qismdan <!DOCTYPE html> dan boshlanib </h3> tegigacha kesib tashlayman
$uzg = file_get_contents(''.$_SERVER['QUERY_STRING']);
preg_match(|'<!DOCTYPE html>'(.*?)'</h3>'|is,'',$uzg); // qirqib tashlangan belgilarni orniga hechnarsa yozmiyman men shuning uchun is dan keyin '' bosh qiymat qoydim
//va pastki qismdan kerakmas joylarni qirqib tashlayman
//span tegidan boshlab html ning yopilish tegigacha
preg_match(|'<span>'(.*?)'</html>'|is,'',$uzg);
//va garblangan malumotni ekranga chiqaramiz
echo $uzg;
?>

va bizda faqat quyidagi yozuvlar ekranga chiqadi

parser haqida kim ma'lumot bera oladi??? lparser bu grabberning akasi garablangan malumotlarni o'zingizning bazangizga yozib borish yani malumotlardan to'liq kopiya olish.
grabberda esa shunchaki boshqa saytni sizni saytizda ko'rsatish holos

Parser buyruq kodlari bazaga yoxishga mysql koldlari shular haqida kim ma'lumot bera oladi?me hali to'liq parser tuzishni o'rganganim yo'q lekin tushuncha bor grablangan sahifani to'liq keraksiz joylarini qirqib kerakli malumotlarni explode(); funksiyasi orqali massiv korinishiga ovolib insert orqali bazaga yozib olsa b'ladi.
bu oddiy matnli malumotlarni parser qilish uchun

sekin sekin o'rganamiz izlanib
