CakePHP's "saveAll" need over 3 minutes to save? - php

Question

I am making an application using CakePHP. I made an action which uses saveAll function.
And I thought it works well, because it doesn't need so much data, but it took over 3 minutes to save using saveAll, or other save function.
Does anyone find my mistakes?
phpMyadmin's columns:
id, rank, school_detail_id, total_score, school_name,
(there is about 300~400 data)
public function rank_update(){
$check_scores = $this->ClubScore->find('all', array('fields'=>array('id','total_score')));
$check_scores2 = Set::sort($check_scores, "{n}.ClubScore.total_score","DESC");
$rank_id=0;
$temp_score=0;
$temp = null;
$for_count=0;
foreach ($check_scores2 as $check_score):
if($temp_score != $check_score['ClubScore']['total_score']){
$rank_id++;
$temp_score = $check_score['ClubScore']['total_score'];
// make ranking by score. same score is same ranking.
}
$this->ClubScore->id = $check_score['ClubScore']['id'];
$this->ClubScore->saveField('rank', $rank_id);
endforeach;
}

Answer 1

Divide the query from foreach to simpler approach
get distinct total_score in desc order
$data = $this->ClubScore->find('all', array('fields'=>array('DISTINCT total_score'), 'order' => 'total_score DESC'));
and then simply save the key as rank for each total_score using updateAll and foreach

Thank you very much Abhishek and AgRizzo ,Nunser!!
Now, I've completely solved this problem. It takes only 1 or 2 seconds!!!!!
Here is the source code.
public function rank_update(){
$data = $this->ClubScore->find('all', array('fields'=>array('DISTINCT total_score'), 'order' => 'total_score DESC'));
$check_scores = $this->ClubScore->find('all', array('fields'=>array('id','total_score')));
$check_scores2 = Set::sort($check_scores, "{n}.ClubScore.total_score","DESC");
$ii = 0;
$temp = 0;
foreach($check_scores2 as $scores):
if($data[$ii]['ClubScore']['total_score']
== $scores['ClubScore']['total_score']){
$temp=$ii+1;
}else{
$ii++;
$temp=$ii+1;
}
$update_arr[] = array(
'ClubScore' => array(
'id' => $scores['ClubScore']['id'],
'rank' =>$temp,
)
);
endforeach;
$update_arr = Set::sort($update_arr, "{n}.ClubScore.id","ASC");
var_dump($update_arr);
foreach($update_arr as $update_arrs):
$this->ClubScore->updateAll(
array(
'ClubScore.rank' => $update_arrs['ClubScore']['rank'],
),
array(
'ClubScore.id' => $update_arrs['ClubScore']['id'],
)
);
endforeach;
}
Thank you very much.
Best regards.
