// 一個簡單的html表單
<form action="action.php" method="post">
  <p>姓名: <input type="text" name="name" /></p>
  <p>年齡: <input type="text" name="age" /></p>
  <p><input type="submit" /></p>
</form>
 
// action.php 接收表單數據, 使用超全局變量
%_POST["name"]
%_POST["age"]
<?php echo htmlspecialchars($_POST['name']); ?>
<?php echo (int)$_POST['age']; ?>
// 這就是最簡單的表單提交,及數據接收

PHP教程
<?php
 
echo "Hello World!";
 
// 當文件為純PHP時,最好在末尾刪除PHP結束標志
//?>

PHP教程
// 在一對開始和結束之外的內容,都會被PHP解釋器忽略.也便是html標簽和PHP代碼混合的那種,跟jsp,asp一樣...
<p>This is going to be ignored by PHP and displayed by the browser.</p>
<?php echo 'While this is going to be parsed.'; ?>
<p>This will also be ignored by PHP and displayed by the browser.</p>
 
// 使用條件,高級分離
<?php if ($expression == true): ?>

PHP教程
<?php
$a_bool = TRUE;  // a boolean
$a_str = "foo"; // a string
$a_str2 = 'foo'; // a string
$an_int = 12;   // an integer
 
echo gettype($a_bool); // prints out: boolean
echo gettype($a_str); // prints out: string
 
// If this is an integer, increment it by four
if (is_int($an_int)) {
  $an_int += 4;
}
 
// If $bool is a string, print it out
// (does not print out anything)
if (is_string($a_bool)) {
  echo "String: $a_bool";
}
?>

PHP教程
echo (int)2.9; // 輸出 2
echo round(2.555, 2) // 輸出 2.56
// 決不要將未知的分數強制轉換為 integer,這樣有時會導致弗成預料的結果.
<?php
echo (int) ( (0.1+0.7) * 10 ); // 顯示 7!
?>

PHP教程
<?php
$a = 1.234;
$b = 1.2e3;
$c = 7E-10;
?>

PHP教程
<?php
$a = 123;
echo '$a'; // 輸出 $a
echo "$a"; // 輸出 123, 轉義字符 '\'
 
$str = <<<'EOD'
Example of string
spanning multiple lines
using nowdoc syntax.
EOD;
 
?>

PHP教程
<?php
$array = array(
  "foo" => "bar",
  "bar" => "foo",
);
 
// 自PHP 5.4 起
$array = [
  "foo" => "bar",
  "bar" => "foo",
]
// key 可以是 integer 或 string 類型
// key 值為可選項, 如果未指定,則使用之前用過最大的integer鍵名加上1作為新鍵名
?>
 
// 要修改某個值,通過其鍵名給該單元賦一個新值.
// 要刪除某個鍵值對,對其調用 unset() 函數.

PHP教程
<?php
class foo{
  function do_foo(){
    echo "Doing foo.";
  }
}
// 用 new 實例化一個類
$f = new foo;
$f->do_foo;

PHP教程
<?php
 
$a = 1;
// 值傳遞賦值 
$b = $a
// 引用賦值
$c = &$a
 
// global 癥結字
global ； $GLOBALS
