php str_replace() 搜索中的重复词

Question

尝试使用搜索和替换一些内容str_replace()。如果 the 是唯一的，它工作正常$find，但是一旦$find有重复的单词，整个事情就搞砸了。

例如 The style1will be applyed on both$find[0] && $find[1]因为两者都是Lorem Ipsum，同样适用于dummy。

如何处理这种情况？

$find = Array(

    [0] => Lorem Ipsum 

    [1] => Lorem Ipsum 

    [2] => typesetting 

    [3] => dummy 

    [4] => dummy 

);

$replace = Array(

    [0] => style1

    [1] => style2

    [2] => style3

    [3] => style4

    [4] => style5

);

$string = "Lorem Ipsum is simply dummy text of the printing and typesetting industry. 

           Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, 

           when an unknown printer took a galley of type and scrambled it to make a type specimen book.";

$result = str_replace($find,$replace,$string);

echo $result;

您可以使用此问题str_replace_first中描述的实现，并迭代您的和数组，仅替换数组中每个值的一次出现：$find$replace$findfunction str_replace_first($search, $replace, $subject) {    if (($pos = strpos($subject, $search)) !== false) {        return substr_replace($subject, $replace, $pos, strlen($search));    }    return $subject;}$result = $string;foreach ($find as $key => $search) {    $result = str_replace_first($search, $replace[$key], $result);}echo $result;输出：style1 is simply style4 text of the printing and style3 industry. style2 has been the industry's standard style5 text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.
