引号中的Php变量

Question

我有一个php变量

$objOrdd['delivery_address']

我想用引号发送它的值，即字符串。我怎样才能做到这一点？

我已尝试"{$objOrdd['delivery_address']}"和". $objOrdd['delivery_address'] ."，但它不起作用！

Answer 1

interpolate中有多种方法可以解决 concatenate / PHP 变量：

// the test
$arr['fox'] = "fox jumps over the ";

// ----------------------

// double quotes: different ways
$str = "The quick brown ".$arr['fox']."lazy dog"; // concat
echo $str."<br>";
# output: The quick brown fox jumps over the lazy dog

$str = "The quick brown {$arr['fox']}lazy dog";  // interp.
echo $str."<br>";
# output: The quick brown fox jumps over the lazy dog

$str = "The quick brown ${arr['fox']}lazy dog";  // interp.
echo $str."<br>";
# output: The quick brown fox jumps over the lazy dog

// ----------------------

// for single quotes concat
$str = 'The quick brown '.$arr['fox'].'lazy dog';
echo $str."<br>";
# output: The quick brown fox jumps over the lazy dog

// ----------------------

// or even use sprintf
$str = sprintf('The quick brown %slazy dog', $arr['fox']);
echo $str."<br>";
# output: The quick brown fox jumps over the lazy dog

当然还有不止这些。我希望尽可能连接。

Answer 2

Suposse $objOrdd['delivery_address'] = "foo"

否则

$myVariable = "'" . $objOrdd['delivery_address'] . "'"

如果您执行echo $myVariable，则会输出'foo'

您可以将{char替换为{或任何您想要的...

Answer 3

你的意思是这样的：

$var = "'".$objOrdd['delivery_address']."'";

或者

$var = '"'.$objOrdd['delivery_address'].'"';

Answer 4

您确定不是在寻找json_encode ($objOrdd['delivery_address'])吗？

Answer 5

addslashes - 使用斜杠引用字符串      

   // Outputs: Is your name O\'reilly?
   echo addslashes($str);
 ?>

Answer 6

1. 您可以使用类型转换以字符串形式发送数据。例如：$ myText =（string）$ myVar;

   结帐：Php variable in quotes

2. 如果要为变量添加引号，则需要将其连接起来。
