fgetcsv（）不使用$ _POST中的变量$ delimiter

I can't get fgetcsv() to work with a variable from $_POST

(  delimiter = (string)$_POST['delimiter'];)

I works if I specify: $delimiter = "\t";

but not when I use: $delimiter = (string)$_POST['delimiter'];

  1. HTML

    <html>
<body>
<form enctype="multipart/form-data" action="upload.php" method="post">
        1) Select a delimiter.<br />
        <input type="radio" name="delimiter" value="\t"checked="yes" /> Tab<br />
        <input type="radio" name="delimiter" value=" "/> Space<br />
        <input type="radio" name="delimiter" value=","/> Comma<br />
        <input type="radio" name="delimiter" value=";"/> Semicolon<br /><br />
        <input type="hidden" name="MAX_FILE_SIZE" value="1000">
        2) Send this file: <input name="userfile" type="file"><br /><br />
        3) <input type="submit" value="Send Info">
</form>
<br />
</body>
</html>

Already $_POST is a string. Why do you need (string) in front of the $_POST? Just remove it. Just have:

delimiter = $_POST['delimiter'];

This should work.

Also, you should not use fgetcsv, as you aren't fetching a file. You need str_getcsv.

str_getcsv($_POST["csv"], $_POST['delimiter']);

Why not make it foolproof like this:

 $options = array(0=> "\t", 1 => "
");
 $delimiter = $options[ (int) $_POST['delimiter'] ];

And use the keys of your options instead of the delimiter itself. Safer and foolproof.

I came across this issue and resolve it by following code:

$delimiter = $_POST['delimiter'];
$delimiter = str_replace("\\t","\t",$delimiter);

Pretty late, but hope it help someone being crazy about this mystery.
