Get an array through if statement - php

Question

I have a array that I want to get using an if statement. This is what I have so far:
if($expPositive[0] <= 5 ){
$data = array();
$data[$i] = $user_id;
$i++;
}
$data_arr = $data;
print_r($data_arr);
When I run print_r($data_arr), this is the result:
Array ( [1] => 105 )
Sometimes the index is 0; i.e.:
Array ( [0] => 96 )
I would like to get this value in an if statement.
Can anyone help me figure this thing out? Any help is greatly appreciated.

Try this:
if($expPositive[0] <= 5 ){
$data = array();
$data[$i] = $user_id;
$i++;
}
$data_arr = $data;
print_r($data_arr);
$temp_key=array_keys($data_arr);
//Now $temp_key will contain keys of the array data_arr
//if $data_arr=Array([1]=>105),$temp_key[0] will have the value **1**
//if $data_arr=Array([0]=>96),$temp_key[0] will have the value **0**
//Now you can use if condition like this:
if($data_arr[$temp_key[0]/*some condition*/)
{
///your code
}
