以下代码在执行FOREACH LOOP时非常慢地运行，然后使用表cabang中的数据进行过滤并插入到名为part_rak的表中。
过滤循环遍历excel文件中的每一行，然后循环基于comma分隔符
过滤循环
if (explode(",", $rowData[0][14]) > 1) {
foreach (explode(",", $rowData[0][14]) as $key => $value2) {
$data = array(
"rak_part_id" => $last,
"rak_cabang_id" => $this->spareparts_m->get_cabang_id_by_code("B"),
"rak_code" => $value2,
"rak_created_at"=> date('Y-m-d H:i:s')
);
$this->db->insert("part_rak",$data);
}
}else{
foreach (explode("|", $cabang) as $key => $value) {
$data = array(
"rak_part_id" => $last,
"rak_cabang_id" => $value,
"rak_code" => $expRak[$key],
"rak_created_at"=> date('Y-m-d H:i:s')
);
$this->db->insert("part_rak",$data);
}
}
这是我的模型方法 get_cabang_id_by_code
public function get_cabang_id_by_code($cabang_code)
{
$q = $this->db->get_where("cabang",array("cabang_code" => $cabang_code));
return $q->result_array()[0]['cabang_id'];
}
对于能改善脚本性能的任何建议，我将不胜感激。
下面是我完整的导入源代码
