无法在PHP中解析时间字符串

问题描述：

I need to create a DateTime from the value received from a form. The problem is that the value is received like a string: "2016-10-10T08:29:06.959Z" and I need to received like 2016-10-10T08:29:06.959Z without quotes, because if I receive with quotes I've got the next error:

DateTime::__construct(): Failed to parse time string ("2016-10-14T22:00:00.000Z") at position 0 ("): Unexpected character

When I try to transform the value to a DateTime with:

$fechaHasta = new DateTime($params["fechaHasta"]);

If I try to use:

$fecha2 = DateTime::createFromFormat("d-m-Y H:i:s", $data["fechaHasta"]);

I've got an empty object in $fecha2.

The form from where I send the data is:

<form id = "formSearch" class = "menu-table" method = "post" action = "<?php echo $this->basePath('/privado/actividades-planificadas/pai/exportdatatoexcel'); ?>">
    <input type = "hidden" name = "codigoPPM" value = "{{searchForm.codigoPPM}}" />
    <input type = "hidden" name = "fechaDesde" value = {{searchForm.dt1}} />
    <input type = "hidden" name = "fechaHasta" value = {{searchForm.dt2}} />
    <input type = "hidden" name = "estado" value = "{{searchForm.estadoSelected.id}}" />
    <button type = "submit">
        Exportar datos a Excel&nbsp;&nbsp;&nbsp;<img title = "Exportar tabla a Excel" src = "/img/logo-excel.png" />
    </button>
</form>

So, what I have to do to send the value without quotes or transform the value received in DateTime.

我需要根据从表单收到的值创建一个DateTime。问题是收到的值就像一个字符串：“2016-10-10T08：29：06.959Z”我需要收到类似2016-10-10T08：29：06.959Z code>的引号，因为如果我收到引号，我会收到下一个错误： p>

 
  DateTime :: __ construct（）：无法解析时间字符串（“2016-10-14T22：  00：00.000Z“）位置0（”）：意外字符 p> 
  blockquote> 
 
 
当我尝试将值转换为DateTime时： p> 
  
 
  $ fechaHasta = new DateTime（$ params [“fechaHasta”]）; 
  code>  pre> 
 
 如果我尝试使用： p>  
 
 
  $ fecha2 = DateTime :: createFromFormat（“dmY H：i：s”，$ data [“fechaHasta”]）; 
  code>  pre> 
 
  我在$ fecha2中有一个空对象。 p> 
 
 
我发送数据的表单是： p> 
 
 
 ＆lt  ; form id =“formSearch”class =“menu-table”method =“post”action =“＆lt;？php echo $ this-＆gt; basePath（'/ privado / actividades-planificadas / pai / exportdatatoexcel'）;  ？＆gt;“＆gt; 
＆lt; input type =”hidden“name =”codigoPPM“value =”{{searchForm.codigoPPM}}“/＆gt; 
＆lt; input type =”hidden“name =”fechaDesde“  value = {{searchForm.dt1}} /＆gt; 
＆lt; input type =“hidden”name =“fechaHasta”value = {{searchForm.dt2}} /＆gt; 
＆lt; input type =“hidden”name  =“estado”value =“{{searchForm.estadoSelected.id}}”/＆gt; 
＆lt; button type =“submit”＆gt; 
 Exportar datos a Excel＆amp; nbsp;＆amp; nbsp;＆amp; nbsp;＆lt;  ; img title =“Exportar tabla a Excel”src =“/ img / logo-excel.png”/＆gt; 
＆lt; / button＆gt; 
＆lt; / form＆gt; 
  code>  pre> 
  
 那么，我必须做什么来发送没有引号的值或转换DateTime中收到的值。 p> 
  div>

答

$date = '"2016-10-14T22:00:00.000Z"';
=> ""2016-10-14T22:00:00.000Z""

$fechaHasta = new DateTime($date);
Exception with message 'DateTime::__construct(): Failed to parse time string ("2016-10-14T22:00:00.000Z") at position 0 ("): Unexpected character'

$fechaHasta = new DateTime(trim($date, '"')); /* « notice the trim */
=> DateTime {#174
     +"date": "2016-10-14 22:00:00.000000",
     +"timezone_type": 2,
     +"timezone": "Z",
   }

So you just trim the " away:

$fechaHasta = new DateTime(trim($params["fechaHasta"], '"'));

This should work fine.

答

try strtotime function and you can set your required format as well.

example:

$date = date('Y-m-d H:i:s' , strtotime("2016-10-14T22:00:00.000Z"))

答

function trim() has option to remove specific characters from string: e.g.:

echo trim('example"','"');

will output: example
