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;

Answer 1

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$find

function 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.
