Question

I need to parse text file in PHP. Pleas see below, I have uploaded it as an image. I need to get the fields market in yellow.

Tried many ways, but not confidence of any. Could somebody help me?

Answer 1

You can process the file with regular expression and some tokenizing. it appears that your field seperater value is '/' and record separator is '\\r\\n\\r\\n'.

$string = "data"; //lets assume your data is contained in one string
$records = preg_split("/^[\r\n\s]+$/", $string); 
//this line assume your file contains dos formatting, change to "/\r\r/" for osx and "/\n\n/" for unix

$data = array();
foreach ($records as $record) { 
     $fields = explode("/", $records);
     $data[] = array($fields[2], $fields[3], $fields[7], $fields[16);
}

var_dump($data);

Please note that the record separator is important and you will need to adjust it based on the file encoding.

Update. i have improved the record separator to be an empty line rather than two consecutive new lines.

Try the following:

$pattern[] = '#[\d]{02}-[\d]{2}-[\d]{2}/[\d]{2}\s[A-Z]{1}\s[\d]{2}#';
$pattern[] = '#EVENT=[A-Z]{3,}#';
$pattern[] = '#AFLR=[\d]{3}-[\d]{3}#';
$res = array();
foreach ($pattern as $key => $value){
    if (preg_match_all($value, $text, $matches)){
        $res[] = $matches[0];
    } else {
        $res[] = NULL;
    }
}

It looks like EVENT and AFLR are variable names that will remain constant, so I hardcoded those letters. If that's not the case, let me know.
