为什么print_r后会多出数组
function getFile() {
$i = 0;
foreach ( $_FILES as $file ) {
if (is_string ( $file ['name'] )) {
$file [$i] = $file;
$i ++;
} elseif (is_array ( $file ['name'] )) {
foreach ( $file['name'] as $key => $val ) {
$file [$i] ['name'] = $file ['name'] [$key];
$file [$i] ['type'] = $file ['type'] [$key];
$file [$i] ['tmp_name'] = $file ['tmp_name'] [$key];
$file [$i] ['error'] = $file ['error'] [$key];
$file [$i] ['size'] = $file ['size'] [$key];
$i ++;
}
}
}
return ($file);
}
Array
