How do you put an array into a string and then index the string using laravel 5

Question

Ok, So I'm running to this problem i"m trying to split/ index the values in a column in my database. So i put the I've been trying to put it into a string, and all the combination I have tried should work, but everytime I try to split the value i keep getting this error Array to string conversion and the errors shows my database as appose to a string or even at the very least a column. Now sorry if my code at this point looks like more work than it should be haha. That was out of desperation and a attempt to get it to work.

this my controller:

public function FSC_List($id)
{

    $fsg_find_id = fsgdata::find($id);
    $fsc_list_all = fscdata::all();
    $fsc_find_id = fscdata::find($id);
    $num_match = fscdata::all()->toArray();
    $fsc_num_col = fscdata::lists('fsc_number');
    $newstring = implode("",$fsc_num_col);
    $final = $newstring.str_split(0,2); 

return View('FSC_views.FSC_List', compact('fsg_find_id','fsc_list_all',
        'fsc_find_id', 'num_match', 'fsc_num_col', 'newstring','final'));
}

This is my view:

@extends('layout.master')
@section('content')
<div class="figure"><img src="/Content/images/figure2.jpg" /></div>
<div class="main">
    <h2>Search Results for FSG Number: {{ $fsg_find_id->fsg_number }}</h2>
        <ul>

        @foreach($fsc_num_col as $fsc_find_id->fsg_number)
            @if($fsg_find_id->fsg_number == $final);
                <a href='/NSN_list={{ $fsc_find_id->id }}'>{{$fsc_find_id->fsc_number}}</a></br>
            @endif
        @endforeach
    </ul>
</div>
@endsection

Note my goal is to have 2 numbers chosen by the users to match up with the first 2 digits of a bunch of 4 digit numbers in a database and to grab all of those that meet that criteria. Thanks in advance to anyone who can help.

The immediate issue looks like this line:

$final = $newstring.str_split(0,2);

Basically, you are trying to combine a string $newstring with an array str_split(0, 2) which is why you are getting the Array to string conversion error. Take a look at the manual entry for str_split - it doesn't look like you understand it properly.

If you are trying to get the first two characters of a string then you should be using substr. Something like:

$full_string = 'abcdefg';
$first_two = substr($full_string, 0, 2);  # $first_two = 'ab'

this is probably not the best practice, but this is how I went about it, if anyone knows how to index more than one character at a time, by all means share haha.

@foreach($fsc_list_all as $fsc_find_id)
    @if($fsg_find_id->fsg_number[0] == $fsc_find_id->fsc_number{0} &&
      $fsg_find_id->fsg_number[1] == $fsc_find_id->fsc_number{1})

          <a href='/NSN_list={{ $fsc_find_id->id }}'>{{$fsc_find_id->fsc_number}}</a></br>

     @endif
@endforeach
