[Resolved] simple: Replace multiple spaces

[leatherback]

Hi,

I have text files, with colums of data in them. I would like to grab the content of these files, and get each colum, by first reading the file:

$content = file('file.txt')

and then getting each value into an array:

$currentrow = explode (" ", $content[$i]);

Now I have the problem that the colums are seperated by unequal number of spaces (one row there might be 6 spaces between rows, on the next there might be 4, it is a formatted datafile..).

Now I would like to replace all occasions of " " (double space) with " " (Single space).
I know I should use regular expressions, but I have no clue how to use them/where to start, and the manual is not te best resource to learn regular expr. I have found...

Anybody who can help me out with a line of code??

Hi

try somethin like this:

$regEx1="/\s{1,}/";
 $StringWithLessSpaces = preg_replace( $regEx1, " ", $StringWithLotsOfSpaces );

This seems to work:

  $line90 = ereg_replace(" {2,}", " ", $fcontents[90]);

Is this the right way of doing it?

if you just want to replace spaces ( as in 0x20 ) then it's ok, the \s option replaces all space-like characters (tabs etc). the {2,} is better than the {1,) of course....

Ah,

OK. One day.. I will master all options in PhP (Will be there soon, building a huge GUI for dataprocessing..).

thanks!
