Quitar comillas en algunas partes de toda una cadena

[juandedios]

Hola, tengo esta cadena

Código PHP:

[{"id":"1","title":"Josue Ismael","allDay":"true","start":"2010-07-02 00:00:00","end":"2010-07-02 00:30:00"},{"id":"2","title":"Josue Ismael","allDay":"false","start":"2010-07-02 16:00:00","end":"2010-07-02 18:30:00"},{"id":"3","title":"prueba ","allDay":"false","start":"2010-07-16 08:00:00","end":"2010-07-16 14:30:00"},{"id":"4","title":"prueba ","allDay":"true","start":"2010-07-09 19:00:00","end":"2010-07-09 19:30:00"},{"id":"5","title":"prueba ","allDay":"true","start":"2010-07-09 19:00:00","end":"2010-07-09 19:30:00"},{"id":"6","title":"prueba ","allDay":"true","start":"2010-07-16 00:00:00","end":"2010-07-16 00:30:00"},{"id":"7","title":"prueba ","allDay":"false","start":"2010-07-16 08:00:00","end":"2010-07-16 14:30:00"},{"id":"8","title":"prueba ","allDay":"true","start":"2010-07-09 19:00:00","end":"2010-07-09 19:30:00"},{"id":"9","title":"Josue Ismael","allDay":"false","start":"2010-07-01 19:00:00","end":"2010-07-01 19:30:00"}]
 

Pero quiero quitarle las comillas a todos los false. Hay forma de hacerlo?

Código PHP:

  $cadena='[{"id":"1","title":"Josue Ismael","allDay":"true","start":"2010-07-02 00:00:00","end":"2010-07-02 00:30:00"},{"id":"2","title":"Josue Ismael","allDay":"false","start":"2010-07-02 16:00:00","end":"2010-07-02 18:30:00"},{"id":"3","title":"prueba ","allDay":"false","start":"2010-07-16 08:00:00","end":"2010-07-16 14:30:00"},{"id":"4","title":"prueba ","allDay":"true","start":"2010-07-09 19:00:00","end":"2010-07-09 19:30:00"},{"id":"5","title":"prueba ","allDay":"true","start":"2010-07-09 19:00:00","end":"2010-07-09 19:30:00"},{"id":"6","title":"prueba ","allDay":"true","start":"2010-07-16 00:00:00","end":"2010-07-16 00:30:00"},{"id":"7","title":"prueba ","allDay":"false","start":"2010-07-16 08:00:00","end":"2010-07-16 14:30:00"},{"id":"8","title":"prueba ","allDay":"true","start":"2010-07-09 19:00:00","end":"2010-07-09 19:30:00"},{"id":"9","title":"Josue Ismael","allDay":"false","start":"2010-07-01 19:00:00","end":"2010-07-01 19:30:00"}]';

$cadena=str_replace('"false"', 'false', $cadena); 
   

si además querés quitarle comillas a los "true" también:

Código PHP:

  $cadena=str_replace(array('"false"', '"true"'), array('false', 'true'), $cadena);

Hola. prueba con esto:

$json={"id":"1","title":"Josue Ismael","allDay":"true","start":"2010-07-02 00:00:00","end":"2010-07-02 00:30:00"}

$json=str_replace ( "\"false\"" , "false" , $json );

Suerte
