PHP MySQL Google Chart JSON - Tam Örnek
Bir sürü Google Grafik veri kaynağı olarak MySQL tablo verileri kullanarak oluşturmak için iyi bir örnek bulmak için aradım. Birkaç gün sonra aradım ve birkaç örnek Google Grafik (pasta, çubuk, sütun, tablo) PHP ve MySQL bir arada kullanarak oluşturmak için kullanılabilir olduğunu fark etti. Sonunda bir örnek çalışma başardı.
Daha önce StackOverflow çok yardım aldım, bu sefer bazı döneceğim.
İki örnek var; birisi Ajax kullanır ve diğer değildir. Bugün, sadece non-Ajax örnek göstereceğim.
Kullanımı:
Requirements: PHP, Apache and MySQL Installation: --- Create a database by using phpMyAdmin and name it "chart" --- Create a table by using phpMyAdmin and name it "googlechart" and make sure table has only two columns as I have used two columns. However, you can use more than 2 columns if you like but you have to change the code a little bit for that --- Specify column names as follows: "weekly_task" and "percentage" --- Insert some data into the table --- For the percentage column only use a number --------------------------------- example data: Table (googlechart) --------------------------------- weekly_task percentage ----------- ---------- Sleep 30 Watching Movie 10 job 40 Exercise 20

<?php
$con=mysql_connect("localhost","Username","Password") or die("Failed to connect with database!!!!");

// This example will display a pie chart. If you need other charts such as a Bar chart, you will need to modify the code a little to make it work with bar chart and other charts
$sth = mysql_query("SELECT * FROM chart");
