php脚本的后面名为.php，代码放置在下面的括号里面：
<"htmlcode"><"hallo world"; "htmlcode"><"htmlcode"><!DOCTYPE html> <html> <body> <"Hello World!<br>"; echo "Hello World!<br>"; EcHo "Hello World!<br>"; "htmlcode"><"red"; $Color="black"; echo "my car is " . $color . "<br>"; echo "my car is " . $Color . "<br>"; "htmlcode"><"<p>测试函数内部的变量：</p>"; echo "变量 x 是：$x"; echo "<br>"; echo "变量 y 是：$y"; } myTest(); echo "<p>测试函数之外的变量：</p>"; echo "变量 x 是：$x"; echo "<br>"; echo "变量 y 是：$y"; "htmlcode"><"htmlcode"><"htmlcode"><"htmlcode"><"Hello world!","world"); "htmlcode"><"GREETING", "Welcome to W3School.com.cn!"); echo GREETING; "htmlcode"><"H"); if ($t<"10") { echo "Have a good morning!"; } elseif ($t<"20") { echo "Have a good day!"; } else { echo "Have a good night!"; } "htmlcode"><"Number 1"; break; case 2: echo "Number 2"; break; case 3: echo "Number 3"; break; default: echo "No number between 1 and 3"; } "htmlcode"><"red","green","blue","yellow"); foreach ($colors as $value) { echo "$value <br>"; } "function" 开头：function functionName() {
被执行的代码;
}
举个例子：<"Hello world!"; } writeMsg(); // 调用函数 "$fname Zhang. Born in $year <br>"; } familyName("Li","1975"); familyName("Hong","1978"); familyName("Tao","1983"); "The height is : $minheight <br>"; } setHeight(350); setHeight(); // 将使用默认值 50 setHeight(135); setHeight(80); "5 + 10 = " . sum(5,10) . "<br>"; echo "7 + 13 = " . sum(7,13) . "<br>"; echo "2 + 4 = " . sum(2,4); "htmlcode">$cars=array("Volvo","BMW","SAAB"); <"Volvo","BMW","SAAB"); echo "I like " . $cars[0] . ", " . $cars[1] . " and " . $cars[2] . "."; "Volvo","BMW","SAAB"); echo count($cars); "Volvo","BMW","SAAB"); $arrlength=count($cars); for($x=0;$x<$arrlength;$x++) { echo $cars[$x]; echo "<br>"; } "htmlcode">$age=array("Peter"=>"35","Ben"=>"37","Joe"=>"43");或
$age['Peter']="35"; $age['Ben']="37"; $age['Joe']="43"; <"Bill"=>"35","Steve"=>"37","Peter"=>"43"); echo "Peter is " . $age['Peter'] . " years old."; "Bill"=>"35","Steve"=>"37","Peter"=>"43"); foreach($age as $x=>$x_value) { echo "Key=" . $x . ", Value=" . $x_value; echo "<br>"; } "htmlcode"><"Bill"=>"35","Steve"=>"37","Peter"=>"43"); asort($age); "Bill"=>"35","Steve"=>"37","Peter"=>"43"); ksort($age); "post" 的 HTML 表单后的表单数据。也常用于传递变量。$_GET:$_GET 也可用于收集提交 HTML 表单 (method="get") 之后的表单数据。 $_FILES $_ENV $_COOKIE $_SESSION 其他内容可以在表单处理中找到。

3月20日消息，近期博主@数码闲聊站 透露，原定三月份发布的华为新旗舰P70系列延期发布，预计4月份上市。
而博主@定焦数码 爆料，华为的P70系列在定位上已经超过了Mate60，成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢？
根据目前爆料的消息来看，华为P70系列将推出三个版本，其中P70和P70 Pro采用了三角形的摄像头模组设计，而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智，但辨识度绝对拉满。
