Converting string to number problem

[acsandras@gmail.com]

I am trying to extract data from an iso-8859-1 encoded XML document. I
open the file, and read each line after each other, and extract some
values. These values are behaving oddly, though.

I can display them as strings:
echo $value; // Returns 0.4
echo "'$value'"; // Returns '0.4'

But I can not convert them into float:
echo floatval($value ); // Returns 0

I did some debugging, which shows that the string length is 18, and not
3 as I axpected.
echo strlen($value); // Returns 18

The encoding is ASCII:
echo mb_detect_encod ing($value); // Returns ASCII

Does anybody have an idea what this could be? I am using PHP 4.3.4.
Thanks in advance, best regards;
András

Try

for ( $i = 0; $i < strlen($v); ++$i )
printf(' %02d', ord($v{$i}));

and see what comes out.

The problem was that I tried to send the following string into the
function:

"<value>0.4 </value>"

When echoing the value and viewing the results in IE, IE parsed <value>
as an HTML tag, and only showed '0.4'. I changed headeren to return
text/plain document, and I realised the problem this way.

Oh right :) Well, always do at least this when investigating string
contents: echo '<pre>'.htmlspe cialchars($s).' </pre>' (or indeed, change
content-type to text/plain).
