how strip off white space ,  ?

i have input in wrapper create,

[b]       bold       [/b]

so before turning text bold, want strip off white spaces , &nbsp, , turn [b]bold[/b],

$this->content = preg_replace("/\[(.*?)\]\s\s+(.*?)\s\s+\[\/(.*?)\]/", "[$1]$2[/$3]", $this->content);

but not work! can help please?

there no need regex based solution. can utilize str_replace as:

$input = "[b]       bold       [/b]"; $input = str_replace(array(' ',' '),'',$input); echo trim($input); // prints [b]bold[/b]

php regex preg-replace whitespace
