[英]Replace all the occurrence even with regex php
I need to replace all the occurrence of the string World [*] : with 2000. 我需要将所有出现的字符串World [*]替换为2000。
Output: 20002000hello 输出: 20002000hello
How can I achieve that? 我该如何实现? I am currently using the below code but it is not working.
我目前正在使用以下代码,但无法正常工作。
preg_replace("/World [(.*?)] : /", "2000", "World [23] : World[125] : hello",-1)
You can use: 您可以使用:
$out = preg_replace('/World\s*\[.*?\] : /', "2000", "World [23] : World[125] : hello");
//=> 20002000hello
[
and ]
are special regex meta characters that need to escaped and make space after World
optional with 0 or more matches. [
和]
是特殊的正则表达式元字符,需要转义并在World
之后的空格为0或更多匹配项。
I have this 我有这个
/(World \[.*?\] : )/
