[英]str_replace with arrays
$a = $_GET['a'];
$d = array("æ", "ø", "å", "Æ", "Ø", "Å");
$e = array("æ", "ø", "å", "Æ", "Ø", "Å");
$new = str_replace("$d","$e","$a");
echo $new;
Can anybody tell me what I'm doing wrong here. 谁能告诉我我在做什么错。 It works perfectly fine if I just write: 如果我只写:
$a = $_GET['a'];
new = str_replace("ø","ø","$a");
echo $new;
Then atleast the "ø" is replaced, but I really want to do it with two arrays instead of replacing one letter at a time, 6 times... 然后至少要替换“ø”,但是我真的想用两个数组来代替而不是一次替换一个字母6次...
$new = str_replace($d, $e, $a);
You're passing variables, not a strings that consist of variables. 您传递的是变量,而不是包含变量的字符串。
If you compare outputs in this code 如果您在此代码中比较输出
$a = array(123);
var_dump($a);
var_dump("$a");
you'll notice, that the first one is an array, and the second one is a string with array implicitly casted to a string. 您会注意到,第一个是数组,第二个是带有隐式转换为字符串的数组的字符串。
