Question

I want to add $variable only if there isn’t a key with the same value in array $insertar["Atributos"].

$insertar["Atributos"][] = $variable;

I can do it using a foreach to check beforehand if $variable is stored and insert only if it isn’t but I want to know if there is an easier way.

Answer 1

To be clear:

I want to add $variable only if there isn’t a key with the same value in array $insertar["Atributos"].

# check if $variable exists as a value in $insertar["Atributos"], and not a key
if (in_array($variable, $insertar["Atributos"])) {
    # add $variable as a VALUE to the array
    $insertar["Atributos"][] = $variable;
}
