Use PHP's str_replace() function to replace multiple texts in a string

In PHP, the str_replace() function is a very commonly used string processing function , can be used to replace specified text in a string. This article will use specific code examples to introduce how to use the str_replace() function to replace multiple texts in a string.

• $replace: Replacement text, which can be a string or a string array.
• $subject: The source string to be searched and replaced, which can be a string or a string array.

Here is an example that demonstrates how to use the str_replace() function to replace multiple text in a string.

<?php
// 需要被替换的文本
$search = array("apple", "orange", "banana");

// 替换文本
$replace = array("苹果", "橙子", "香蕉");

// 源字符串
$subject = "I have an apple, an orange and a banana.";

// 替换文本
$result = str_replace($search, $replace, $subject);

As shown above, you can easily replace multiple texts in a string using the str_replace() function. Set the text to be replaced in the $search array, set the replaced text in the $replace array, and search and replace in the $subject string. The replacement result will be stored in $result and can be output or used as needed.

In addition to the method of replacing strings demonstrated in the example, the str_replace() function can also search and replace using a single string. When the $search and $replace arguments are passed as strings rather than arrays, only the first matching text will be replaced.

Summary:
The str_replace() function is a powerful string processing function that can be used to replace multiple texts in a string. By setting the $search and $replace parameters, you can search and replace specified text in the $subject string.
