php - Invalid argument supplied for foreach() on iterating json array -

i have json:

[{"nombre":"example1","idcomplejo":"1","canchafk":"1","cantidadturnos":"35"}, {"nombre":"example2","idcomplejo":"3","canchafk":"6","cantidadturnos":"29"}, {"nombre":"example3","idcomplejo":"4","canchafk":"7","cantidadturnos":"6"}, {"nombre":"example4","idcomplejo":"5","canchafk":"8","cantidadturnos":"4"}, {"nombre":"example5","idcomplejo":"5","canchafk":"9","cantidadturnos":"2"}] 

i wanna show in table html page, have error:

invalid argument supplied foreach()

this part of code getting error:

<table cellpadding="0" cellspacing="0">     <thead>         <tr>             <th>id complejo></th>             <th># cancha></th>             <th>cantidad turnos></th>         </tr>     </thead>     <tbody>         <?php foreach ($cantidadturnos $turno): ?>         <tr>              <td><?= h($turno->idcomplejo) ?></td>             <td><?= h($turno->canchafk) ?></td>             <td><?= h($turno->cantidadturnos) ?></td>         </tr>         <?php endforeach; ?>     </tbody> </table> 

the var_dump of cantidadturnos json put above. help

the json in form of javascript object. php cannot read needs parse json json_decode(), this:

$cantidadturnos = json_decode('[{"nombre":"example1","idcomplejo":"1","canchafk":"1","cantidadturnos":"35"}, {"nombre":"example2","idcomplejo":"3","canchafk":"6","cantidadturnos":"29"}, {"nombre":"example3","idcomplejo":"4","canchafk":"7","cantidadturnos":"6"}, {"nombre":"example4","idcomplejo":"5","canchafk":"8","cantidadturnos":"4"}, {"nombre":"example5","idcomplejo":"5","canchafk":"9","cantidadturnos":"2"}]'); 

now $cantidadturnos in form of array foreach can work this:

foreach ($cantidadturnos $turno) {     // }
