需要在数组的每个字符串中搜索值以构造另一个数组

Question

I have this array:

Array
(
    [count] => 12
    [6] => CN=G_Information_Services,CN=Users,DC=hccc,DC=campus
    [7] => CN=WEBadmin,CN=Users,DC=hccc,DC=campus
    [9] => CN=G_ISDept,CN=Users,DC=hccc,DC=campus
    [10] => CN=STAFF,CN=Users,DC=hccc,DC=campus
)

and I want to create an array of values that consist of the value between the first CN= and , of each array value below.

I probably will have to loop thru the array above, do a regex search for the first occurrence of cn and the value that follows it

I am not sure what I am doing wrong.

I need the final result to be an array that resembles this:

array('G_Information_Services', 'WEBadmin', 'G_ISDept', 'STAFF');

Answer 1

Use preg_match on each of the array values to get only the first corresponding CN value.

$found = array();

foreach ($arr AS $values) {
    if (preg_match('/CN=([^,]+),/',$values,$matches))
        $found[] = $matches[1];
}

Output

Array
(
    [0] => G_Information_Services
    [1] => WEBadmin
    [2] => G_ISDept
    [3] => STAFF
)
