If you can find a suitable scanf-format, you might be able to do it all with one fscanf. If you have to change things later, this could be useful, or not. Probably not, but you are the judge.

It is not fixed format. I need to parse ddd into a var in order to decide if I want to process that row. If I do I need to put ccc and bbb into vars to process it. I need to do this during a while loop one record at a time. Any... (11 Replies)

splfileobject.fscanf
SPLFILEOBJECT.FSCANF(3) 1 SPLFILEOBJECT.FSCANF(3)SplFileObject::fscanf - Parses input from file according to a format
SYNOPSIS
public mixed SplFileObject::fscanf (string $format, [mixed &$...])
DESCRIPTION
Reads a line from the file and interprets it according to the specified $format, which is described in the documentation for sprintf(3).
Any whitespace in the $format string matches any whitespace in the line from the file. This means that even a tab in the format string
can match a single space character in the input stream.
PARAMETERS
o $format
- The specified format as described in the sprintf(3) documentation.
o $...
- The optional assigned values.
RETURN VALUES
If only one parameter is passed to this method, the values parsed will be returned as an array. Otherwise, if optional parameters are
passed, the function will return the number of assigned values. The optional parameters must be passed by reference.
EXAMPLES
Example #1
SplFileObject::fscanf example
<?php
$file = new SplFileObject("misc.txt");
while ($userinfo = $file->fscanf("%s %s %s")) {
list ($name, $profession, $countrycode) = $userinfo;
// Do something with $name $profession $countrycode
}
?>
