Question

I want to remove all quotes from a string INCLUDE nested quotes.

it does not works for nested qoutes:

preg_replace("/\[quote(.*?)\](.*?)\[\/quote\]/i","", $text);

this works for something like:

[quote=admin]Welcome to RegExr 0.3b, an intuitive tool for learning, writing, and testing Regular Expressions. Key features include: [/quote]

but not for:

[quote=admin]Welcome to RegExr 0.3b, [quote] an intuitive tool for learning, [/quote] writing, and testing Regular Expressions. Key features include: [/quote]

would like to remove all qoute blocks

I think your mistake simply is the question mark in your expression.

Try preg_replace("/\[quote(.*?)\](.*)\[\/quote\]/i","", $text);

With your example posted in your edit:

$text = '[quote=admin]Welcome to RegExr 0.3b, [quote] an intuitive tool for learning, [/quote] writing, and testing Regular Expressions. Key features include: [/quote]';
$cleared = preg_replace("/\[quote(.*?)\](.*)\[\/quote\]/i","", $text);

var_dump($cleared);
// -> string(0) ""
