搜索字符串数组值替换一个词 [英] Search a string replace a word with array's value

问题描述

的想法是要搜索的某些单词串，并根据特定的阵列它们变成别的东西。让我告诉你我是什么意思。

The idea is to search a string for certain words and change them into something else according to specific array. Let me show you what I mean.

$string = "hello buddy, I'm your friend or maybe a fellow";      

比方说，朋友是脏话。我想这个词变成我想要的。所以，我提出这样的：

Let's say friends is a swear word. I want to change this word to what I want. So I made this:

$swears = array(
"friend" => "fri**d",
"buddy"  => "bu**y",
"fellow" => "fe**ow"
);

我要根据数组的键搜索的字符串和替换它与它的价值。我没有在网上搜索我得到的是根据数组的键数组中替换值。所以想后，我想出了这一点：

I want to search the string according to the array's key and replace it with it's value. I did search the web all I get is replace a value in the array according to an array key. so after trying I came up with this:

$string = "hello buddy, I'm your friend or maybe a fellow";  

$swears = array(
"friend" => "fri**d",
"buddy"  => "bu**y",
"fellow" => "fe**ow"
);

$foreach  = $string; 
foreach($swears as $bad => $good){
$foreach       = str_replace($bad,$good,$foreach);
$filtered =  $foreach;
 }
echo $filtered;

我知道它的工作原理，但有一个简单的方法，我觉得我变得复杂了整个事情。如果我很好，这可能会引起一个问题，如果我有大串，或者需要时间来处理它。

I know it works, but is there an easy way I feel I complicated the whole thing. If I'm good, is it possible it may cause a problem, if I had large string, or take time to process it.

推荐答案

str_replace函数 可能与的搜索词阵列并提供阵列替代品的

<?php
$string = "hello buddy, I'm your friend or maybe a fellow";

$swears = array(
    "friend" => "fri**d",
    "buddy"  => "bu**y",
    "fellow" => "fe**ow"
);

echo str_replace(array_keys($swears), array_values($swears), $string);
?>

显示：

hello bu**y, I'm your fri**d or maybe a fe**ow
