Masters, my array looks like this
array(2) {
[14] => array(6) {

<code>["job_name"] => string(44) "苹果,香蕉,苹果"</code>
Copy after login
Copy after login

}
[3] => array(6) {

<code>["job_name"] => string(44) "梨子,梨子,西红柿"</code>
Copy after login
Copy after login

}
}

I want it to be

array(2) {
[14] => array(6) {

<code>["job_name"] => string(44) "苹果2,香蕉1"</code>
Copy after login
Copy after login

}
[3] => array(6) {

<code>["job_name"] => string(44) "梨子2,西红柿1"</code>
Copy after login
Copy after login

}
}

Is this Jiang Zi difficult? T.T Does anyone know how to do it? Q.Q

<code class="php">array_walk($arr, function(&$item) {
    $item['job_name'] = join(',', array_unique(explode(',', $item['job_name'])));
});</code>

I didn’t see the question clearly, here is the revised answer

<code class="php">array_walk($arr, function(&$item) {
    $after = array_values(array_unique(explode(',', $item['job_name'])));
    foreach ($after as $key=>$value) {
        preg_match_all("/$value/", $item['job_name'], $matches);
        $after[$key] = $value . count($matches[0]);
    }
    $item['job_name'] = join(',', $after);
});</code>

It means that the job_name field in this two-dimensional array, if there are duplicates, just set the corresponding number of repetitions after the repetition, right?

<code class="php">foreach ($arr as $fruits){
    $fruits_array = explode(',',$fruits['job_name']);
    $count_array = array();
    foreach ($fruits_array as $fruit){
        $count_array[$fruit][] =1;
    }
    $sum_data =array();
    foreach ($count_array as $fruit=>$fruit_array){
        $sum_data[] = $fruit.  count($fruit_array);
    }
    $sum_data = implode(',',$sum_data);
    $return_data[]["job_name"] = $sum_data;

}</code>

<code>function dealArr($arr=array()){
    foreach ($arr as $key => $value) {
        $a0[$key] = explode(',',$value['job_name']);//分割字符串
        $a1[$key] = array_count_values($a0[$key]);//统计个数
        $temp=array();
        foreach ($a1[$key] as $key2 => $value2) {
            $temp[$key2]=$key2.$value2;
        }
        $res[$key]['job_name']=implode(',',$temp);//字符串转数组
        
    } 
    return $res;
}</code>

Error checking related to input arrays has not been processed yet

<code>$arr[14]['job_name']="苹果,香蕉,苹果";
$arr[3]['job_name']="梨子,梨子,西红柿";
var_dump(dealArr($arr));

<code>foreach ($arr as &$val){

    $return = array_count_values($job_name_array);
