Simple PHP string replace?
提问by Abhi
I have this code:
我有这个代码：
$abc = ' Hello "Guys" , Goodmorning';
I want to replace every occurrence of "(double quotes) by $^so that string becomes
我想替换"（双引号）的每次出现，$^以便字符串变为
'Hello $^Guys$^ , Goodmorning'
I am new to PHP; in Java we can do this very easily by calling the string class replaceAllfunction, but how do I do it in PHP? I can't find the easy way on Google without using regular expressions.
我是 PHP 新手；在 Java 中，我们可以通过调用 string 类replaceAll函数很容易地做到这一点，但我如何在 PHP 中做到这一点？如果不使用正则表达式，我在 Google 上找不到简单的方法。
What is some syntax with or without the use of regular expressions?
使用或不使用正则表达式的语法是什么？

String replace function is used to replace string. Your syntax is wrong. You have to use php string functionlike below example. First of all, think about first and two values and replace in third. Let's have a look.
字符串替换函数用于替换字符串。你的语法是错误的。您必须使用如下示例的php 字符串函数。首先，考虑第一个和两个值并替换第三个。我们来看一下。
<?php
echo str_replace("Hello", "HI", "Hello Hyman ");
?>
It produces the output.
它产生输出。
HI Hyman.
