大神们 我的数组长这个样子
array(2) {
[14] => array(6) {
["job_name"] => string(44) "苹果,香蕉,苹果"}
[3] => array(6) {
["job_name"] => string(44) "梨子,梨子,西红柿"}
}
我想让它变成
array(2) {
[14] => array(6) {
["job_name"] => string(44) "苹果2,香蕉1"}
[3] => array(6) {
["job_name"] => string(44) "梨子2,西红柿1"}
}
这个酱紫 会不会很难T.T 有朋友会么Q.Q
foreach ($arr as &$val){
$job_name_array = explode(',',$val['job_name']);
$return = array_count_values($job_name_array);
$str = '';
foreach ($return as $key => $value){
$str .= $key.$value.',';
}
$str = rtrim($str,",");
$val['job_name'] = $str;
}意思就是这个二维数组中的job_name字段，如果有重复的，就在重复的后面设置对应的重复数即可，对不！
foreach ($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"] = $sum_data;
}array_walk($arr, function(&$item) {
$item['job_name'] = join(',', array_unique(explode(',', $item['job_name'])));
});没看清楚题目, 下面是修改后的答案
array_walk($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(',', $after);
});function dealArr($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;
}输入数组相关的错误检查暂未处理
$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));
