Loop an array of array
So I know how to traverse an array of even key => value (associative), but I have a weird array where I need to walk through it and print out values:
$object_array = array(
'type' => 'I am type',
array(
'property' => 'value',
'property_2' => 'value_2'
)
);
What I thought I could do is:
foreach($object as $key=>$vlaue){
//what now?
}
So as you can see I am lost, how do I walk through the next array?
You can try:
function traverse($array) {
foreach ($array as $key => $value) {
if (is_array($value)) {
traverse($array);
continue;
}
echo $value;
}
}
foreach($object as $key=>$value){
if( is_array($value) ) {
foreach($value as $key2=>$value2) {
//stuff happens
}
} else {
//other stuff
]
}
Try:
foreach($object_array as $value) {
if(!is_array($value))
echo $value;
else {
foreach($value as $m)
echo $m;
}
}
In your for loop you could do:
if(is_array($object[$key]))
//process inner array here
It depends on how deep your arrays go, if you have arrays of arrays of arrays...and so on, a different method would be better, but if you just have one level this is a pretty simple way of doing it.
Well, you could do something like this:
foreach($object_array as $key=>$value)
{
if(is_array($value) {
foreach($value as $k=>$v) {
echo $k." - ".$v;
}
} else {
echo $key." - ".$value;
}
}
An alternative with array_walk_recursive():
function mydebug($value, $key) {
echo $key . ' => ' . $value . PHP_EOL;
}
array_walk_recursive($object_array, 'mydebug');
Handy if you doing something simple with the values (e.g. just echo ing).
