PHPでキーワードを置き換える方法

echo str_replace(array("m","i"),array("n","z"),"my name is jim!")

echo str_replace(array('m','i'),'n',"my name is jim!");

<?php 
$vowels = array("a", "e", "i", "o", "u", "A", "E", "I", "O", "U");
$onlyconsonants = str_replace($vowels, "","Hello World of PHP");
echo $onlyconsonants;
?>

str_replace(find,replace,string,count)

<?php
//把字符串 "Hello world!" 中的字符 "world" 替换为 "Shanghai"：

echo str_replace("world","Shanghai","Hello world!");
?>

$arr="abcdefg";
$replace=array('h','i','j','k','l','m','n');
$find=array('a','b','c','d','e','f','g');
$str=str_replace($find,$replace,$arr);
var_dump($str);
var_dump($arr);die;
