Question

从下面的代码中，这是我想要实现的：如果$ get_friends查询找到的citizenID是1和2.我希望while循环首先获取1的所有行然后执行同样的2.我现在的代码只有它的唯一检索最后一行为1和2.请帮助。

var timezones = [
  { value: '-12.0', str: '(GMT -12:00) Eniwetok, Kwajalein' },
  { value: '-11.0', str: '(GMT -11:00) Midway Island, Samoa' },
  { value: '-10.0', str: '(GMT -10:00) Hawaii' },
  { value: '-9.0', str: '(GMT -9:00) Alaska' },

  { value: '-4.0', str: '(GMT -4:00) Atlantic Time (Canada), Caracas, La Paz' },
  { value: '-3.5', str: '(GMT -3:30) Newfoundland' },
  { value: '-3.0', str: '(GMT -3:00) Brazil, Buenos Aires, Georgetown' },
  { value: '-2.0', str: '(GMT -2:00) Mid-Atlantic' },

  { value: '0.0', str: '(GMT) Western Europe Time, London, Lisbon, Casablanca' },
  { value: '+1.0', str: '(GMT +1:00) Brussels, Copenhagen, Madrid, Paris' },
  { value: '+2.0', str: '(GMT +2:00) Kaliningrad, South Africa' },
  { value: '+3.0', str: '(GMT +3:00) Baghdad, Riyadh, Moscow, St. Petersburg' },
  { value: '+3.5', str: '(GMT +3:30) Tehran' },
  { value: '+4.0', str: '(GMT +4:00) Abu Dhabi, Muscat, Baku, Tbilisi' },
  { value: '+4.5', str: '(GMT +4:30) Kabul' },

  { value: '+9.5', str: '(GMT +9:30) Adelaide, Darwin' },
  { value: '+10.0', str: '(GMT +10:00) Eastern Australia, Guam, Vladivostok' },
  { value: '+11.0', str: '(GMT +11:00) Magadan, Solomon Islands, New Caledonia' },
  { value: '+12.0', str: '(GMT +12:00) Auckland, Wellington, Fiji, Kamchatka' }
];

timezones.forEach(function(tz){
  console.log(tz.value);
  // Next how to calc current hour in the tz.value timezone ?
});

Answer 1

您只使用$row = $result->fetch_assoc();获取一行。

您是否尝试获取用户的所有评论？

因为那样你需要循环使用$result就像你正在使用的while ($row_friends = $results_get_friends->fetch_assoc())

一样

也可以尝试使用prepare和bind_param来avoid possible SQL injection

，而不是连接您的SQL查询

PHP没有像我想的那样循环
