php - 替换单词并保持找到的字符串区分大小写

Question

我正在创建一个 php 应用程序来格式化文件。所以我需要在维护案例的同时应用查找替换过程。

例如，我需要将“员工”替换为“车辆”。

$file_content = "Employees are employees_category MyEmployees kitEMPLOYEESMATCH";
$f = 'employees';
$r = 'vehicles';

echo str_ireplace($f, $r, $file_content);
   

当前输出:

vehicles are vehicles_category Myvehicles kitvehiclesMATCH

期望的输出:

Vehicles are vehicles_category MyVehicles kitVEHICLESMATCH

Answer 1

您可以通过分别替换每个案例来使用类似的东西:

<?php
     $file_content = "Employees are employees_category MyEmployees kitEMPLOYEESMATCH";
     $f = 'employees';
     $r = 'vehicles';

     $res = str_replace($f, $r, $file_content); // replace for lower case
     $res = str_replace(strtoupper($f), strtoupper($r), $res); // replace for upper case
     $res = str_replace(ucwords($f), ucwords($r), $res); // replace for proper case (capital in first letter of word)
     echo $res
   
?>
