In_array with spaces and adding results to same column PHP - php

Question

I have a form that has check boxes and if the selection was not there, they can add text in into a text field other:.
To make it easier to find the other: I am trying to concatenate it with the text input.
$torsList = array('Bi-monthly','Quarterly','Monthly','Seasonal (Mosquito)','One Time ($1 6 month)','Specialty','Free inspection');
function addOther($input)
{
if(in_array($input, $torsList)) {
return $input;
} else {
return 'Other:'.$input;
}
};
I believe the spaces are what are making a false statement when they select an item from the array.
if agent selects seasonal (mosutio) then database column 1 will show seasonal (mosquito)
if agent inputs text then database column 1 will display Other:what ever
Ps: new to php

<label class="choice" for="element_15_3">Monthly</label>
<input id="element_15_4" name="element_15" class="element radio" type="checkbox" value="Seasonal (Mosquito)" />
<label class="choice" for="element_15_4">Seasonal (Mosquito)</label>
<input id="element_15_5" name="element_15" class="element radio" type="checkbox" value="One Time ($1 6 month)" />
<label class="choice" for="element_15_5">One Time ($1 6 month)</label>
<input id="element_15_6" name="element_15" class="element radio" type="checkbox" value="Specialty" />
<label class="choice" for="element_15_6">Specialty</label>
<input id="element_15_7" name="element_15" class="element radio" type="checkbox" value="Free inspection" />
<label class="choice" for="element_15_7">Free inspection</label>
Other:<input id="element_15_8" name="element_15_1" class="element text"
type="text" />
</span>
This is how I'm using the function $TypeOfRecurringService = addOther($_POST['element_15']);

You have a variable scope problem. You defined the variable $torsList outside the function, but you're using it inside the function. If you turn on error_reporting(E_ALL), you'll see that you're getting a warning about an undefined variable.
You need to put the $torsList variable inside the addOther function.
