PHP中的Multi StringReplace

Question

如何将yes替换为1而将no替换为0？ 示例:(不工作！）

str_replace("yes","1",$data,"no","0",$data);

Answer 1

函数str_replace()支持数组参数：

var_dump(
  str_replace(array('yes', 'no'), array('1', '0'), $data)
);

strtr()支持替换数组：

var_dump(
  strtr($data, array('yes' => 1, 'no' => 0))
);

Answer 2

str_replace("yes", "1", str_replace("no", "0", $data));

Answer 3

$data = str_replace("yes","1",$data);
$data = str_replace("no","0",$data);

Answer 4

$str = 'This is yes, this is no';
$str = preg_replace(array('/yes/i', '/no/i'), array('1', '0'), $str);

echo $str; // This is 1, this is 0
