Php- Eliminate characters while reading file

I would I am using PHP. I am reading from a file but I would like to eliminate the following characters from the file wherever they are: '' and { }.

I tried to use the trim function but the characters "',{ and }" are still present in the output:

$txt_file    = file_get_contents('out.txt');
$rows        = explode(",", $txt_file);
array_shift($rows);

foreach($rows as $row => $data)
{
    //get row data
    $row_data = explode(':', $data);
    trim($row,"'");
    trim($row,"{");
    trim($row,"}");
    $info[$row]['state']          = $row_data[0];
    $info[$row]['action']         = $row_data[1];
    echo  $info[$row]['state'] . '<br />';
    echo  $info[$row]['action'] . '<br />';
    echo '<br />';
}

Do you have any idea how to do it? Thanks

I assume you want to remove ' { and } from $row

If it is, then replace 

trim($row,"'");
trim($row,"{");
trim($row,"}");

with 

$row = str_replace(['\'', '{', '}'], '', $row);

Note: trim — Strip whitespace (or other characters) from the beginning and end of a string. Moreover you didn't store trimmed data to any variable so literally you will not get trimmed data. You want to replace characters wherever it is found so use str_replace or preg_replace. Please check PHP manual for more details
