How can I show this array in a grouped way according to the value "cat"?
My array:
$options = array(
array("cat" => "Impresoras","nameProd" => "Impresora 4"),
array("cat" => "Destructoras","nameProd" => "Destructora 3"),
array("cat" => "Impresoras","nameProd" => "Impresora 8"),
array("cat" => "Destructoras","nameProd" => "Destructora 5")
);
I need to print:
Impresoras: Impresora 4, Impresora 8
Destructoras: Destructora 3, Destructora 5
Try this
$options = array(
array("cat" => "Impresoras","nameProd" => "Impresora 4"),
array("cat" => "Destructoras","nameProd" => "Destructora 3"),
array("cat" => "Impresoras","nameProd" => "Impresora 8"),
array("cat" => "Destructoras","nameProd" => "Destructora 5")
);
foreach ($options as $key => $value) {
$nArray[$value['cat']][] = $value['nameProd'];
}
foreach ($nArray as $key => $value) {
echo $key.":".implode(",", $value)."<br>";
}
Output
Impresoras:Impresora 4,Impresora 8
Destructoras:Destructora 3,Destructora 5
Create a new array with the cat as key. Someting like this;
$grouped_categories = array();
foreach ( $options as $option ) {
$grouped_categories[$option['cat']][] = $option['nameProd'];
}
This will output something like;
[
'Impresoras' => ['Impresora 4', 'Impresora 8']
'Destructoras' => [...]
]
How you want to output that array is up to you.
$data = [];
$options = array(
array("cat" => "Impresoras", "nameProd" => "Impresora 4"),
array("cat" => "Destructoras", "nameProd" => "Destructora 3"),
array("cat" => "Impresoras", "nameProd" => "Impresora 8"),
array("cat" => "Destructoras", "nameProd" => "Destructora 5")
);
foreach ($options as $key => $value) {
$data[$value['cat']][] = $value['nameProd'];
};
