先學PHP基礎,再去百度查自己需要的功能的原理,然後去實驗,實驗成功後在網站上使用它。
走完這四步,你才算學會了這門技術的一個功能。
學不會PHP人絕大部分一直在重復第一步 !
w3school上的教程非常的基礎,很容易懂,建議先看完它。然後可以看看php100的視頻教程,這個講得很細很易懂,而且講知識點非常的多,我也是看這個學會的。
還是那句話,看教程只是在背乘法口訣,只會乘法口訣的學生從來都不會做應用題,只有使用它,那才是真正的學習!
最簡單的程序就這樣:
<?php
echo 'Hello, world!';
?>
下載PHP可以在www.php.net下載,選擇windows下的二進制代碼,可以下載安裝包和ZIP包,我喜歡ZIP包,隨便解壓縮到一個文件夾就可以了,例如c:\php\下。雙擊上面保存的(我用記事本編輯)PHP文件,選擇和你剛才解開的c:\php\php.exe關聯就可以了。
