在关联数组中删除逗号

Question

我有一个包含三个关联数组的数组。我试图从价格中删除逗号：

for ($i =1 ; $i<4; $i++) {
foreach ($array[$i]['product'] as $products) {
    str_replace(',', '', $products ['price']);
}
}

Answer 1

for ($i =1 ; $i<4; $i++) {
  foreach ($array[$i]['product'] as $products) {
    $products ['price'] = str_replace(',', '', $products ['price']);
  }
}

您需要将值分配回数组。或者：

for ($i =1 ; $i<4; $i++) {
  foreach ($array[$i]['product'] as $products) {
    $array [$i]['product']['price'] = str_replace(',', '', $products ['price']);
  }
}
