删除字符串周围的第一个' '实例

Question

Hi I have the following situation where I have tags wrapped around my contents and the following input

[hello]

Text here

[/hello]

[hello]

Text here 2

[/hello]

The output is

[hello]

Text here

[/hello]

[hello]

Text here 2

[/hello]

The desired output should be

[hello]
Text here
[/hello][hello]
Text here 2
[/hello]

PS: THanks for the answer, but since its user input, there's a chance of spacing [hello]

Is there a way using php, to trim the first around the opening tag ([hello]) and closing tag([/hello])? Thanks

Answer 1

it's simple, in the other words you want to replace to

$str = "[hello]

Text here

[/hello]

[hello]

Text here 2

[/hello]";
echo str_replace("

", "
", $str);

it will output

[hello]
Text here
[/hello]
[hello]
Text here 2
[/hello]
