复制代码 代码如下:
echo "asd";//字符串
echo "ads$c";//字符串+变量
echo 'ads$c';//字符串 asd$c $c不是变量
echo "sd"."vs";
echo "sd","vs";
echo $a;
echo $a.$b;
echo $a,$b;
echo $a.$b.$c;
echo $a,$b,$c;
echo "kaskd{$c}asd";
echo "kakskd{$arr['lo']}";
echo "kakskd{$obj->a}";
echo "kaskd".$c."kasd";
echo "kaskd".$arr['lo']."kasd";
echo "kaskd".$obj->a."kasd";
echo "kaskd".func($c)."kasd";
echo "kaksk".($a+1)."dkkasd";
echo $c."jaksd";
echo $c,"jaksd";
//php多行输出方法
echo <<<END
This uses the "here document" syntax to output
END;
//输出简写
<?php echo $a;?> <?=$a?>
复制代码 代码如下:
<?php
echo "Hello World";
echo "This spans
multiple lines. The newlines will be
output as well";
echo "This spans\nmultiple lines. The newlines will be\noutput as well.";
echo "Escaping characters is done \"Like this\".";
// You can use variables inside of an echo statement
$foo = "foobar";
$bar = "barbaz";
echo "foo is $foo"; // foo is foobar
// You can also use arrays
$baz = array("value" => "foo");
echo "this is {$baz['value']} !"; // this is foo !
// Using single quotes will print the variable name, not the value
echo 'foo is $foo'; // foo is $foo
// If you are not using any other characters, you can just echo variables
echo $foo; // foobar
echo $foo,$bar; // foobarbarbaz
// Some people prefer passing multiple parameters to echo over concatenation.
echo 'This ', 'string ', 'was ', 'made ', 'with multiple parameters.', chr(10);
echo 'This ' . 'string ' . 'was ' . 'made ' . 'with concatenation.' . "\n";
echo <<<END
This uses the "here document" syntax to output
multiple lines with $variable interpolation. Note
that the here document terminator must appear on a
line with just a semicolon. no extra whitespace!
END;
// Because echo does not behave like a function, the following code is invalid.
($some_var) ? echo 'true' : echo 'false';
// However, the following examples will work:
($some_var) ? print 'true' : print 'false'; // print is also a construct, but
// it behaves like a function, so
// it may be used in this context.
echo $some_var ? 'true': 'false'; // changing the statement around
?>
以下是官方手册说明：
Definition and Usage
定义和用法
The echo() function outputs one or more strings.
echo()函数的作用是：输出一个或多个字符串。
Syntax
语法
echo(strings)
Parameter参数 Description描述
strings Required. One or more strings to be sent to the output
必要参数。指定一个或多个需要被发送到结果中的字符串
Tips and Notes
提示和注意点
Note: The echo() function is not actually a function, so you are not required to use parentheses with it. However, if you want to pass more than one parameter to echo(), using parentheses will generate a parse error.
注意：echo()函数不是一个真正意义上的函数，所以你没有必要一定去使用它。如果你想把多于一个的参数传递给echo()函数，那么使用圆括号“()”将产生错误。
Tip: The echo() function is slightly faster than print().
提示：echo()函数相当于print()函数的简化版本。
Tip: The echo() function has the following shortcut syntax. See example 5.
提示：echo()函数包含下面的简便写法。具体见：案例5。
Example 1
案例1
复制代码 代码如下:
<?php
$str = "Who's Kai Jim?";
echo $str;
echo "<br />";
echo $str."<br />I don't know!";
?>
The output of the code above will be:
上述代码将输出下面的结果：
Who's Kai Jim?Who's Kai Jim?I don't know!
Example 2
案例2
复制代码 代码如下:
<?php
echo "This textspans multiplelines.";
?>
The output of the code above will be:
上述代码将输出下面的结果：
This text spans multiple lines.
Example 3
案例3
复制代码 代码如下:
<?php
echo 'This ','string ','was ','made ','with multiple parameters';
?>
The output of the code above will be:
上述代码将输出下面的结果：
This string was made with multiple parameters
Example 4
案例4
Difference of single and double quotes. Single quotes will print the variable name, not the value:
区别单引号(')和双引号(”)的不同。单引号将输出变量名，而不是变量的值：
复制代码 代码如下:
<?php
$color = "red";
echo "Roses are $color";
echo "<br />";
echo 'Roses are $color';
?>
The output of the code above will be:
上述代码将输出下面的结果：
Roses are redRoses are $color
Example 5
案例5
Shortcut syntax:
简写（捷径）语法：
复制代码 代码如下:
<html><body>
<?php
$color = "red";
?><p>Roses are <?=$color?></p></body></html>
echo "asd";//字符串
echo "ads$c";//字符串+变量
echo 'ads$c';//字符串 asd$c $c不是变量

echo "kaskd".$obj->a."kasd";
echo "kaskd".func($c)."kasd";
echo "kaksk".($a+1)."dkkasd";

echo $c,"jaksd";

稳了！魔兽国服回归的3条重磅消息！官宣时间再确认！
昨天有一位朋友在大神群里分享，自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址，com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后，确实是网易的网址，也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情，因为以前都没有出现这样的情况，现在突然提示跳转到国服战网的网址，是不是说明了简体中文客户端已经开始进行更新了呢？
