php arrays in arrays - does it contain this string

I have what looks like a rather strange array, to me anyway, this is the result of a print_r ($info) and of var_export; :

print_r ($info);

output

Array ( [count] => 1 [0] => 
Array ( [sessiontimeout] => Array ( [count] => 1 [0] => 0 ) [0] => sessiontimeout [description] => Array ( [count] => 1 [0] => Admin group ) [1] => description [cn] => Array ( [count] => 1 [0] => ldap-admin ) [2] => cn [objectclass] => Array ( [count] => 2 [0] => top [1] => GroupV2 ) [3] => objectclass [enabled] => Array ( [count] => 1 [0] => TRUE ) [4] => enabled [uniquemember] => Array ( [count] => 2 [0] => uid=username1,cn=users,dc=abc,dc=net [1] => uid=username2,cn=users,dc=abc,dc=net )
[5] => uniquemember [count] => 6 [dn] => cn=ldap-admin,cn=staff,cn=company,cn=groups,dc=abc,dc=net ) )

var_export($info);
array ( 'count' => 1, 0 => array ( 'sessiontimeout' => array ( 'count' => 1, 0 => '0', ), 0 => 'sessiontimeout', 'description' => array ( 'count' => 1, 0 => 'Admin group', ), 1 => 'description', 'cn' => array ( 'count' => 1, 0 => 'ldap-admin', ), 2 => 'cn', 'objectclass' => array ( 'count' => 2, 0 => 'top', 1 => 'oGroupV2', ), 3 => 'objectclass', 'enabled' => array ( 'count' => 1, 0 => 'TRUE', ), 4 => 'enabled', 'uniquemember' => array ( 'count' => 2, 0 => 'uid=username1,cn=users,dc=jhc,dc=net', 1 => 'uid=username2,cn=users,dc=abc,dc=net', ), 5 => 'uniquemember', 'count' => 6, 'dn' => 'cn=ldap-admin,cn=staff,cn=company,cn=groups,dc=abc,dc=net', ), )

im only interested in the uniquemember uid= parts. I have been trying to set a variable that is uid=usernameX and then check if the variable contains the username i have been given previously in my code. It looks like this:

for ($i=0; $i<=$info["count"]; $i++) {
  $uid = $info[$i]["uniquemember"][$i];

  if (strpos($info, "uid=$username")) {
    echo "$username  valid";
  } else {
    echo $username not valid";
  }
}

As far as i can tell my variable uid is not being reset to the second instance of uid=, in this case it should be "uid=username2"

If the username provided is username1 i get the output

username1 valid

If the username is username2 i get

username2 not valid

When i would expect it to be valid.

It may be useful if you break it up into smaller parts so you can more clearly see what is happening. One thing to note is that strpos can return 0 if it matches on the first char (which it will) and the way you are writing the if statement, its only checking for truthy or falsy. Change it to use !== false for a proper comparison.

// Get unique members array
$uniqueMembers = $info[0]['uniquemember'];

// Get unique member count
$memberCount = (int) $uniqueMembers['count'];

// Loop through members
for ($i = 0; $i < $memberCount; $i++) {

    // Get the UID string
    $uid = $uniqueMembers[$i];

    // Check if it matches the supplied username
    if (strpos($uid, "uid=$username") !== false) {
       echo "$username is valid!";
    } else {
       echo "$username is not valid!";
    }

}
