How can I extract the colors of this json?
[{
"item1": "si",
"item2": "no",
"item3":
[
{
"color": "azul",
"tipo": "circulo"
},
{
"color": "rojo",
"tipo": "triangulo"
},
{
"color": "verde",
"tipo": "cuadrado"
}
]
}
]
This is what I do and if I extract item1 and item2, but in item3 it shows me the Array pabra.
$array = json_decode($data);
foreach($array as $colors=>$color){
echo "$colors:<br>";
while (list($clave,$valor)=each($color)){
echo "$clave=$valor<br>";
}
}
First, what you do to decode:
$array = json_decode($data);
You are $ data parsing as an object. By the name of the variable I interpret that you want an array, so
$array = json_decode($data,true);
Done this, if you know that your item3 has the form item3 = >[{color,tipo},{color,tipo},{color,tipo}] and you want to print its content.
foreach($array['item3'] as $pares){
echo "Colores:<br>";
foreach($pares as $llave=>$valor) {
echo "$llave = $valor <br>";
}
}
I should give you:
Colores:
color=azul,
tipo=circulo
Colores:
color= rojo,
tipo=triangulo
Colores:
color=verde,
tipo=cuadrado
This may not be exactly what you need to do. If you want an algorithm to go through a generic array, checking if any of its keys has an array value, it is more or less the same with a little more added logic.
try this
foreach($data as $colors => $color){
echo "$colors:<br>";
while (list($clave,$valor)=each($color)){
if (is_array($valor)) {
$string = '';
foreach ($valor as $v) {
$string .= ' '.$v['color'];
}
$valor = $string;
}
echo "$clave = $valor<br>";
}
}
