Question

我正在使用用PHP编写的CRM，我需要创建一组高度使用的电子邮件地址，例如：

emailFirst@domain.com
emailThird@domain.com
emailThird@domain.com
emailScond@domain.com 
emailThird@domain.com
emailScond@domain.com

这里是我想要的：

emailThird@domain.com (3)
emailScond@domain.com (2)
emailFirst@domain.com (1)

我尝试使用php中的代码：

$string_emails = "emailFirst@domain.com emailThird@domain.com emailThird@domain.com 
emailScond@domain.com emailThird@domain.com emailScond@domain.com";
$emails = str_word_count($string_emails, 1);
$ret = array_count_values($emails );
print_r($ret);

但是没有运气，它只是向我展示。

感谢。

Answer 1

$string_emails = "emailFirst@domain.com emailThird@domain.com 
emailThird@domain.com emailScond@domain.com emailThird@domain.com 
emailScond@domain.com";
// we create an array with the values if you really want to have an str for your values
$emails = explode( ' ', $string_emails );

$emails_list = array();

foreach($emails as $item)
{
    $emails_list[$item] = $emails_list[$item]+1;
}

print_r($emails_list);

Answer 2

$string_emails = "emailFirst@domain.com emailThird@domain.com 
emailThird@domain.com emailScond@domain.com emailThird@domain.com 
emailScond@domain.com";
$emails = explode($string_emails, ' ');




print_r(array_count_values($emails));

输出：

Array ( 
[emailFirst@domain.com] => 1 
[emailThird@domain.com] => 3 
[emailScond@domain.com] => 2 )

Answer 3

这个怎么样

$emails = "emailFirst@domain.com emailThird@domain.com emailThird@domain.com 
emailScond@domain.com emailThird@domain.com emailScond@domain.com";

$array = array();
$array = explode(" ",$emails);

if(sizeof($array) > 0 ){
 $final_array = array();
 foreach($array as $key=>$val){
  $final_array[$val] += 1 ;
 }
}

print_r($final_array);

输出::

Array ( [emailFirst@domain.com] => 1 [emailThird@domain.com] => 3 [ emailScond@domain.com] => 1 [emailScond@domain.com] => 1 )

发现问题，额外的空间可能会导致问题，因此此行将解决此问题

   $final_array[trim($val)] += 1 ;

而不是

   $final_array[$val] += 1 ;

将列表中高度重要的电子邮件地址分组
