正则表达式出错？ [关闭]

Regexp :

preg_match('#^(\\w+)( | array )(\\w+)(?:|\\=(.*))$#', $line, $mtch)

Text :

integer  udg_plc = 0
integer array udg_time
string array udg_plname
player  array udg_dlforpl
multiboard udg_LastTable= null
integer array udg_kill1

As a result there is no matches. How to correct?

This is because there are more than 1 space in your input

/^(\w+)( +| +array +)(\w+)(?:| +\=(.*))$/

Use + quantifier to match 1 to many spaces
