PHP Remove Text Between [ and ] Parentheses
php, regex, string
Solution
You just need to remove everything between `[]` with the `preg_replace` function.
$a = 'hello, [how][are] you';
echo preg_replace('#\s*\[.+\]\s*#U', ' ', $a); // hello, you
The regex catches every spaces before and after and replace it with a single space.
Be careful, `[` and `]` are reserved characters in regex, you need to escape them with `\`. If you want to keep the possibility to write `[]` in your string (without anything between), you can transform the `.*` in `.+`.
Problem
I need to remove text included between [ and ] parentheses (and parentheses, too). For example: Hello, [how are you] Must become: Hello, And, a string like: hello, [how][are] you must become: hello, you There is a regula expression to do that?
