Reading file and removing commas

[Michael Connolly]

Hi everyone Ive a problem that i need solving essentially i have a file that i want to read from a form using php simple enough and then to add a function to read the file line by line and remove the commas of the text file im relatively new to this and would really really appreciate the help .

i have got this with pseudo code but putting it into action im not sure.

  read file contents into a string find first comma in that string with str_pos, result in $comma while ($comma) {   remove comma from $content using substr   find first comma with str_pos   } result is string without any commas 

[something else]

It sounds like a long winded way to remove commas from a string.
A quicker and easier way would be something like:

<?
    $file = file_get_contents('file.txt');
    echo str_replace(',', '', $file);
?>
