What is the difference between the following two formats when you move a directory to another table of contents? Solving!!

Mobile Development php PHP Mobile Directory

(Move directory)
if (!empty ($testCategoryData)) {
$data [0] = Array_shift ($testCategoryData);
$data [0][' children '] = $testCategoryData;
}


(Mobile use case)
$data = Array ();
$data [0]= $testCategoryData [0];
for ($index = 1; $index < count ($testCategoryData); $index + +) {
$data [0][' Children '] [$index-1] = $testCategoryData [$index];
}

Reply to discussion (solution)

The difference is that the latter is laborious

Can you put the latter for the next processing principle to say, I have been using the first method, the second is occasionally seen, thank you

for ($index = 1; $index < count ($testCategoryData), $index + +) {//start with subscript 1 until the last
$data [0][' Children '] [$index-1] = $testCategoryData [$index]; Copy each element to the target array
}

I appreciate it, thank you.
