novice for variables questions

#1
[eluser]syntaxerror[/eluser]
hi,
can anyone please help me with these simple question, i think.
i have codes in php
Code:
$vtag1 = substr($file1[$x],178,1);
    $vtag2 = substr($file2[$x],178,1);
    $page1 = substr($file1[$x],0,4);
    $page2 = substr($file2[$x],0,4);
    $name1 = substr($file1[$x],7,78);
    $name2 = substr($file2[$x],7,78);
    $addr1 = substr($file1[$x], 1, 78);
    $addr2 = substr($file2[$x], 1, 78);
    $city1 = substr($file1[$x], 79, 30);
    $city2 = substr($file2[$x], 79, 30);
    $state1 = substr($file1[$x], 110, 2);
    $state2 = substr($file2[$x], 110, 2);
    $zc1 = substr($file1[$x], 112, 5);
    $zc2 = substr($file2[$x], 112, 5);
    $tf1 = substr($file1[$x], 123, 40);
    $tf2 = substr($file2[$x], 123, 40);
    $phone1  = substr($file1[$x], 164, 12);
    $phone2  = substr($file2[$x], 164, 12);
but code igniter doesnt accepts variables like this in controller.
so i have to make $data[....] all variables.
Code:
$data['vtag1'] = substr($data['file1'][$x],178,1);
                        $data['vtag2'] = substr($data['file2'][$x],178,1);
                        $data['name1'] = substr($data['file1'][$x],7,78);
                        $data['name2'] = substr($data['file2'][$x],7,78);
is there shortcut in making variables in controller of codeigniter?
and also how to use for loop in controller?

thanks

what is $file1[$x]

try like this
Code:
$data['vtag1'] = substr($file1[$x],178,1);
$data['vtag2'] = substr($file[$x],178,1);
$data['name1'] = substr($file1[$x],7,78);
$data['name2'] = substr($file2[$x],7,78);



don't use data for these values

thanks,
but there is an error
Code:

BTW my whole function is this
Code:
function process()
    {
        $data['title'] = "DS Validator";
        $data['header'] = "DS Validator";

        $data['qcbase'] = "//asecasianas2/DS_Keying/STATS/QC-DIR/";
        $data['ke']= directory_map($data['kebase'].$_POST["directory"], TRUE);
        $data['qc']= directory_map($data['qcbase'].$_POST["directory"], TRUE);
        $data['kelist'] = count($data['ke']) - 1;
        $data['kelist2'] = $data['kelist']+ 1;
        $data['qclist'] = count($data['qc']) - 1;
        $data['qclist2'] = $data['qclist']+ 1;
        $data['count_comp'] = strcmp($data['kelist2'], $data['qclist2']);
        $data['row_comp'] = strcmp($data['kelist'],$data['qclist']);
        for($x = 0; $x <= $data['qclist']; $x++)
        {
            $data['ke_batch'] = $data['ke'][$x];
            $data['qc_batch'] = $data['qc'][$x];
            $data['file1'] = file($data['kebase'].$_POST["directory"]."/".$data['ke_batch']);
            $data['file2'] = file($data['qcbase'].$_POST["directory"]."/".$data['qc_batch']);
            $data['file2_count'] = count($data['file2']);
            $data['count'] = 1;
                for($x = 0; $x <= $data['file2_count']; $x++)

                            {
                                $data['str'] = $data['vtag1'];
                            }else{
                                $data['str']= 'level2';
                                 }
                            $data['count']++;
                    
                    }
                    $this->load->view('process', $data);
        }

For one, this should be in a model, not the controller. Controllers aren't meant to retrieve and parse files. And it looks like you're scraping a file, so the process is just inherently going to be messy and tedious (messy + tedious != controller). Once you figure out how to get it into the array structure you want, you can then have the model return this array to the controller. The controller could be responsible for passing instructions to the model function that does this (like the paths of file1 and file2, for instance)
