简单的preg_match开始...结束

Question

我想在suche代码中捕获所有出现的“对象”：

object InvalidFilterField3: TUNIField
  FieldType = uftString
  FieldName = 'PRI_SERIAL'
  Caption = sdfgsdfgsdfg
  Category = sdfgsdfgsdfgsdfg
  Opers = [opEqual, opLike, opInList, opIsNull, opIsNotNull]
  DefaultOper = opLike
  FieldIndex = 0
end
object UNIField1: TUNIField
  FieldType = uftDate
  FieldName = 'PRI_DT'
  Caption = sdfgsdfgsdfg
  Category = asdfasdfasdfasdf
  Opers = [opEqual, opNotEqual, opLarger, opSmaller, opEqualOrLarger, opEqualOrSmaller, opBetween, opIsNull, opIsNotNull, opIn]
  DefaultOper = opEqual
  FieldIndex = 1
end

认为必须是/object(.*)end/m，但它不是=（

你需要将dotall修饰符（ s ）传递给模式告诉PCRE一个点意味着任何（包括换行符）和ungreedy修饰符（< strong> U ，更多关于the PHP manual上的贪婪和修饰符）：

preg_match_all('!object(.*)end!sU', $string, $matches);
print_r($matches);
