php - 合并两个数组并替换它们

问题描述：

I want to merge two arrays and replace the text with strtr function.

I was using this before

$text = "cat cow";
$array = array(
"cat" => "dog",
"cow" => "bull"
);
$output = strtr($text, $array);

this returned dog bull...

Now I have two arrays like this...

$a = array("cat", "dog");
$b = array("dog", "bull");

Both the arrays will have values to replace

Now, how do I combine them and replace? I tried $array = $a + $b and array_combine, but they didn't work...

Please Help...

我想合并两个数组并用strtr code>函数替换文本。 p >

我之前使用过这个 p>


  $ text =“cat cow”; 
 $ array = array（
“cat”=＆gt;  “dog”，
“cow”=＆gt;“bull”
）; 
 $ output = strtr（$ text，$ array）; 
  code>  pre> 
 
  这返回 dog bull  code> ...  p> 
 
 
现在我有两个这样的数组...  p> 
 
 

  $  a = array（“cat”，“dog”）; 
 $ b = array（“dog”，“bull”）; 
  code>  pre> 
 
 两个数组都将 有值替换 p> 
 
 
现在，我如何将它们组合并替换？ 我尝试了 $ array = $ a + $ b  code>和 array_combine  code>，但它们没有用...  p> 
 
 
请帮忙。  ..  p>

答

I think two arrays must be

$a = array("cat", "cow");
$b = array("dog", "bull");

And you can use

$c = array_combine($a, $b);
$output = strtr($text, $c);

答

Do you mean merge them to get array('cat','dog','bull')? If so just do:

$array = array_unique(array_merge($a,$b));

答

I dont know how you have tried.

$text = "cat cow";
$array = array(
"cat" => "dog",
"cow" => "bull"
);

$text = "cat cow";

$array = array("cat" => "dog",
"cow" => "bull"
);
$output = strtr($array, $array);
echo $output;
//output -> dog bull


$a = array("cat", "cow");
$b = array("dog", "bull");
$c = array_combine($a,$b);
print_r($c);
$output1 = strtr($text, $c);
echo $output1;
//output -> dog bull

I thing the above code gives you what output you need.

I think you have used the wrong array Check the $a and $b array I hope i have helped you.
