PHP str_replace是否具有大于13个字符的限制？ - php

直到击中第13个字符为止。一旦str_ireplace在cyper数组中击中“ a”，str_ireplace就停止工作。

数组的大小有限制吗？请记住，如果键入“ abgf”，我会得到“ nots”，但是如果键入“ abgrf”，我应该得到“ notes”，那么我就会得到“ notrs”。机架使我的大脑无法解决。

$_cypher = array("n","o","p","q","r","s","t","u","v","w","x","y","z","a","b","c","d","e","f","g","h","i","j","k","l","m");

$_needle = array("a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z");


$_decryptedText = str_ireplace($_cypher, $_needle, $_text);
echo $_decryptedText;

救命？

参考方案

使用strtr^Docs：

$_text = 'abgrf';

$translate = array_combine($_cypher, $_needle);

$_decryptedText = strtr($_text, $translate);

echo $_decryptedText; # notes

Demo

但是，我做错了什么吗？

它将替换每对，在已替换的字符串上一个接一个地替换。因此，如果您替换一个字符然后再次替换，则会发生这种情况：

    r -> e   e -> r
abgrf -> notes -> notrs

您的电子换人是在您进行r换人之后。
