php preg_mahch字符截取

Question

$tt = "Event: Dial  Privilege: call,all  SubEvent: Begin  Channel: Local/0267@from-queue-2962;2  Destination: SIP/601-00001bca  CallerIDNum: 07016317212  CallerIDName: rc07016317212  ConnectedLineNum: 0267  ConnectedLineName: 0267  UniqueID: 1339380988.50590  DestUniqueID: 1339380988.50591  Dialstring: 601";
preg_match("/(CallerIDNum:\s+\d+)\s+.+(UniqueID:\s\d+\.\d+)/",$tt,$out, PREG_OFFSET_CAPTURE,3);希望的结果是　
['CallerIDNum']　＝〉"07016317212" ;
['CallerIDName'] =>"rc07016317212" ;
['ConnectedLineNum']=>"0267";
['ConnectedLineName']=>"0267";
['UniqueID']=>"1339380988.50590";
[DestUniqueID]=>"1339380988.50591";

类型这样，从那个字符串拆分一个名称对应一个值

Answer 3

如$tt里某个名称没有值的话，那拆分后，这个名称的值就由变为将下一个名称填充进去，
。比如　这里$tt　CallerIDNum和UniqueID它们的值均不存在，这样就会错误$tt = "Event: Dial  Privilege: call,all  SubEvent: Begin  Channel: Local/0267@from-queue-2962;2  Destination: SIP/601-00001bca  CallerIDNum:   CallerIDName: rc07016317212  ConnectedLineNum: 0267  ConnectedLineName: 0267  UniqueID: DestUniqueID: 1339380988.50591  Dialstring: 601";
array(10) { 
["Event"]=> string(4) "Dial" 
["Privilege"]=> string(8) "call,all" 
["SubEvent"]=> string(5) "Begin" 
["Channel"]=> string(28) "Local/0267@from-queue-2962;2" 
["Destination"]=> string(16) "SIP/601-00001bca" 
["CallerIDNum"]=> string(13) "CallerIDName:" 这里将下个名称填充了["ConnectedLineNum"]=> string(4) "0267" 
["ConnectedLineName"]=> string(4) "0267" 
["UniqueID"]=> string(13) "DestUniqueID:" 这里将下个名称填充了["Dialstring"]=> string(3) "601" } 
?>

preg_match_all('/(\w+):(\s*?[^\s:]+?|\s*?)(?:\s|$)/',$str,$matches);$arr=array_combine($matches[1],$matches[2]);
print_r($arr);
