How to remove the last 1 arrays because of a name as same. please give me a solution

Answer 1

You can put all the results in an array, only adding them if the namedoesn't already exist:
$products = array();
foreach ($_productCollection as $_product){
$product = $_product->getData();
if (!in_array($product['name'], array_column($products, 'name'))) {
$products[] = $product;
}
}
echo "<PRE>";
print_r($products);

Answer 2

You can splice repeated row which contains the same value:
$res_ar = []; // resultant array
$ar_names = []; // array of unique names
foreach($ar as $ind => $row){
if (in_array($row['name'],$ar_names)){ // if name was before
array_splice($ar,$ind,1); // remove element by its index
} else {
$ar_names[] = $row['name']; // add new name to the unique array of names
$res_ar[] = $row; // saving row with new name value
}
}
Demo
Implementation for your case looks like next:
$res_ar = [];
$ar_names = [];
foreach ($_productCollection as $ind => $_product){
$row = (array)$_product->getData();
if (in_array($row['name'], $ar_names)){
array_splice($_productCollection,$ind,1);
} else {
$ar_names[] = $row['name'];
$res_ar[] = $_product;
}
}

One last version, just keep a track of the names added, but also add the original to the output rather than the array of data...
$output = [];
$existingNames = [];
foreach ($_productCollection as $product){
$productName = $product->getData()['name'];
if ( !isset($existingNames[$productName])) {
$existingNames[$productName] = true;
$output[] = $product;
}
}
