嘗試使用搜索和替換一些內容str_replace()。如果 the 是唯一的，它工作正常$find，但是一旦$find有重復的單詞，整個事情就搞砸了。例如 The style1will be applyed on both$find[0] && $find[1]因為兩者都是Lorem Ipsum，同樣適用于dummy。如何處理這種情況？$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;

您可以使用此問題str_replace_first中描述的實現，并迭代您的和數組，僅替換數組中每個值的一次出現：$find$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;
輸出：
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.
