PHP Schleife durch ein Array auf der Suche nach allen Feldern, die 1 enthalten

Question

Ich habe eine Abfrage, die einen Datensatz sucht, die gut funktioniert. Ich muss dann den Namen aller Felder wiederholen, die mit "Seq" beginnen und "1" enthalten.

meine Frage:

SELECT * FROM ROSE_Hist 
WHERE UniqueID = '1919' AND 1 IN (SeqID0101,SeqID0102,SeqID0103 ,SeqID0104,SeqID0105,SeqID0106,SeqID0107,SeqID0108,SeqID0109,SeqID0110,SeqID0201,SeqID0202,SeqID0203,SeqID0301,SeqID0302,SeqID0303,SeqID0304,SeqID0401,SeqID0402,SeqID0403,SeqID0404,SeqID0501, 
SeqID0502,SeqID0601,SeqID0602,SeqID0701,SeqID0702,SeqID0801,SeqID0802,SeqID0901,SeqID0902,SeqID0903,SeqID1001,SeqID1002,SeqID1003,SeqID1004,SeqID1101,SeqID1102,SeqID1201,SeqID1302,SeqID1303,SeqID1304,SeqID1305, 
SeqID1401,SeqID1402,SeqID1403,SeqID1404,SeqID1405,SeqID1406,SeqID1407,SeqID1408,SeqID1409,SeqID1410,SeqID1411,SeqID1501,SeqID1502,SeqID1504,SeqID1505,SeqID1601,SeqID1602,SeqID1603,SeqID1604,SeqID1605,SeqID1701,SeqID1702,SeqID1703,SeqID1704, 
SeqID1705,SeqID1801,SeqID1802,SeqID1901,SeqID1902,SeqID2001,SeqID2002,SeqID2101,SeqID2102,SeqID2201,SeqID2202,SeqID2203,SeqID2301,SeqID2302,SeqID2401,SeqID2402,SeqID2403,SeqID2501,SeqID2502,SeqID2503,SeqID2601,SeqID2602,SeqID2603,SeqID2701, 
SeqID2702,SeqID2703,SeqID2704,SeqID2801,SeqID2901,SeqID2902,SeqID3001,SeqID3002,SeqID3101,SeqID3201,SeqID3202,SeqID3203,SeqID3204,SeqID3301,SeqID3302,SeqID3401,SeqID3402,SeqID3501,SeqID3502,SeqID3601,SeqID3602,SeqID3603,SeqID3604,SeqID3605, 
SeqID3606,SeqID3701,SeqID3702,SeqID3703,SeqID3704,SeqID3801,SeqID3802,SeqID3803,SeqID3804,SeqID3901,SeqID3902,SeqID3903,SeqID3904,SeqID4001,SeqID4002,SeqID4003,SeqID4101,SeqID4102,SeqID4201,SeqID4202,SeqID4301,SeqID4302,SeqID4303,SeqID4304, 
SeqID4401,SeqID4501,SeqID4502,SeqID4503,SeqID4504,SeqID4505,SeqID4506,SeqID4507,SeqID4508,SeqID4509,SeqID4510,SeqID4511,SeqID4512,SeqID4513,SeqID4514,SeqID4601,SeqID4602,SeqID4603,SeqID4604,SeqID4701,SeqID4702,SeqID4703,SeqID4704,SeqID4705) ORDER BY Room ASC 

Dann brauche ich eine Schleife durch das Ergebnis und ech nur die Felder, die mit „Seq“ und enthalten die Nummer „1“ beginnen.

foreach ($row_RoomAudit as $key => $val) { 
    print "$key = $val\n"; 
} 

Ich habe etwas falsch hier, weil der "Foreach" alle Felder widergibt. Was müsste ich tun, um nur die Feldnamen zu wiederholen, die mit dem Namen "Seq" beginnen und "1" enthalten?

Vielen Dank für Ihre Zeit.

Answer 1

Eine schnelle Abhilfe mit strpos „1“ zu finden und substr

foreach ($row_RoomAudit as $key => $val) { 
     if (strpos($val, '1') !== FALSE && substr($val, 0, 3)=='Seq'){ 
      print "$key = $val\n"; 
     } 
    } 

Answer 2

dass ‚Seq‘ zu finden ist, weil Sie alle Felder AUSWAHL * verwenden. Wenn Sie nur die bestimmte Spalten auswählen möchten, haben Sie Ihre Abfrage zu ändern, dies zu tun:

SELECT SeqID0101,SeqID0102,SeqID0103 ,SeqID0104,SeqID0105,SeqID0106,SeqID0107,SeqID0108,SeqID0109,SeqID0110,SeqID0201,SeqID0202,SeqID0203,SeqID0301,SeqID0302,SeqID0303,SeqID0304,SeqID0401,SeqID0402,SeqID0403,SeqID0404,SeqID0501,

Natürlich innerhalb der Schleife Filterung ist auch eine Möglichkeit, aber es ist besser Praxis nur die Daten anfordern Du brauchst es wirklich. Wenn Sie also nur diese Spalten ausgeben müssen, sollten Sie nur diese Spalten auswählen.
