Removing New line character in Fields PHP

i am trying to upload an excel file and to store its contents in the Mysql database.

i am having a problem in saving the contents.. like

My csv file is in the form of

开发者_运维问答

        "1","aruna","IEEE 
         paper"
        "2","nisha","JOurnal magazine"

actually i am having 2 records and i am using the code

<?php
  $string = file_get_contents( $_FILES["file"]["tmp_name"] );
  //echo $string;

foreach ( explode( "\n", $string ) as $userString )

    {
                 echo $userString;

            }

?> since in the Csv record there is a new line inserted in between IEEE and paper it is dispaying me as 3 records..

How to remove this new line code wise and to modify the code so that only the new line between the records 1 and 2 is considered...

Use fgetcsv to load an parse CSV files.

Maybe you should be using a library to open and modify excel files. Try with XLS Reader.

The fgetcsv command is powerful and useful, you should probably use it. But if you want your original question answered...

1. replace the "good" newlines with some weird token, like @EOL@
2. replace the "bad" newlines with another token, like @NL@
3. replace the first token with a newline
4. parse your data.

like so...

<?php   
    $txt = <<<_TXT
"1","aruna","IEEE 
paper" "2","nisha","JOurnal magazine"
"2","aruna","IEEE paper" "2","nisha","JOurnal magazine"
"3","aruna","IEEE paper" "2","nisha","JOurnal
magazine"
"4","aruna","IEEE paper" "2","nisha","JOurnal magazine"
_TXT;
    $txt = str_replace("\"\n", "@EOL@", $txt);
    $txt = str_replace("\n", "@NL@", $txt);
    $txt = str_replace("@EOL@", "\n", $txt);
    echo $txt;
?>

The output is...

"1","aruna","IEEE @NL@paper" "2","nisha","JOurnal magazine

"2","aruna","IEEE paper" "2","nisha","JOurnal magazine

"3","aruna","IEEE paper" "2","nisha","JOurnal@NL@magazine

"4","aruna","IEEE paper" "2","nisha","JOurnal magazine"
