无法在PHP中解析时间字符串

Question

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.

Answer 1

$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.
