How to replace text in php

Operating system for this tutorial: Windows 10 system, php8.1.3 version, Dell G3 computer.

In PHP, you can use the str_replace() function or the preg_replace() function to replace text.

1. Use the str_replace() function for simple text replacement:

$string = "这是一个示例文本。";
$search = "示例";
$replace = "样例";
newString=strreplace(newString = str_replace(newString=strreplace(search, replace,replace, replace,string);
echo $newString;
Copy after login

2. Use the preg_replace() function for text replacement based on regular expressions:

$string = "这是一个示例文本。";
$pattern = '/示例/u';
$replace = "样例";
newString=pregreplace(newString = preg_replace(newString=pregreplace(pattern, replace,replace, replace,string);
echo $newString;
Copy after login

In this example, we use the /example/u regular expression pattern to match "example" in the string and replace it with "example" using the preg_replace() function.

It should be noted that the preg_replace() function can perform more complex text replacement, such as using regular expression matching patterns, pattern modifiers, etc. The str_replace() function is more suitable for simple string replacement operations.

Choose the appropriate method for text replacement based on your specific needs.
