Hi All,

Using Version 4.3.9 (Stuck with it for now).

Anyhow, I am trying to do formatted output of single digit decimals. I have a form and present you an abbreviated example for getting a month value.

<select class="inform" name="logmonth">
<option value="1">Jan</option>
<option value="2">Feb</option>
<option value="3">Mar</option>
</select>

and upon submit it runs through another php process

//variable set
$logmonth = $_POST[logmonth];

//and my attempt to format the output
fwrite($out,"%02d\n",$logmonth);

so that it will write to a file

and put a leading 0 in front of single digit months.

Example, for February the output to the file would be 02.

The fwrite doesn't seem to work.

Any suggestions would be appreciated.

Thanks


That's because fwrite() doesn't accept a formatting string. You write a string; the third parameter is optional and is the number of bytes to write.

You need fprintf() instead.


fprintf doesn't seem to work for me. It stops things in its tracks and does nothing through the rest of the script beginning at that line.

//I have it as
fprintf($out,"%02d\n",$logmonth);

Is this right?


Enable all errors and display them. On your development system, your php.ini file should always have:

error_reporting=E_ALL
display_errors=on

Sounds to me like J.O. has the right idea.


Wow, I turned on display_errors and Boom! Got some, but there was this fatal one,

Fatal error: Call to undefined function: fprintf() in /<snip>/PostDepProcess.php on line 147

So it is telling me that there is a problem with

fprintf($out,"%02f\n",$logmonth);

although I have been told it looks right. Why would it be an undefined function?

It's a long time since played with php4, fprintf was introduced in php5, it seems like you have to process the string with sprintf() and then write the output to the file.

fwrite($out,sprintf("%02f\n",$logmonth));

I think that should fix your trouble.
