sprintf question

[toshog]

hi all,

very quick and easy....

$totalcharge = 332.0;

echo "<b>Total Charge: ".$totalcharge."</b>";
produces: Total Charge: 332.0

echo "<b>Total Charge: ".$foo = sprintf("%.2f", $totalcharge)."</b>";
produces: Total Charge: 0.00

i need 332.00 of course...

please somebody explain...

thanks..

It's weird...I tried

<?php
$totalCharge = 332.0;
echo "<b>Total Charge: ".$foo = sprintf("%.2f", $totalCharge)."</b>"; 
?>

and it outputted 332.00. I'm using PHP 4.1.2

Anyway, if you separate the assignment statement from the echo statement it should definitely work.

Yeah I tried it and it works perfectly.

Though sprintf() is usually used for strings, it does have a limited option to format floats but perhaps number_format() may be a little bit more usefull.

<?php
$totalCharge = "332.1";
echo "<b>Total Charge: ".$foo = number_format($totalCharge, 2, '.', ',')."</b>"; 
?>

thanks.... i figured that one out...

now i have this issue:

this:
<?
$moo = getallheaders();

echo $foo = $moo["Content-type"];
?>

produces blank page.... this:

<?
$headers = apache_request_headers();

foreach ($headers as $header => $value) {
echo "$header: $value <br />\n";
}

?>

produces error:

....Call to undefined function: apache_request_headers()....

please somebody help...

thanks....

apache_request_headers() requires php 4.3.0 but does exactly the same thing as getallheaders(), they just changed the name.

I don't think there is a key Content-type in the appache headers as i think this is client side. Let me know if im wrong.

apache_response_headers() is server side which does have Content-type as a key.

try

<? 
$moo = apache_response_headers(); 
foreach($moo as $headers => $value)
	{
	echo"<b>$headers</b> $value<br />";
	}
?> 

to echo out the array or

<? 
$moo = apache_response_headers(); 

echo $foo = $moo["Content-Type"]; 
?> 

to echo out the Content-Type.

Note though that apache_response_headers(); is only available on php 4.3.0 so if you get undefined function you probably don't have it loaded.

also note you need the headers in the page eg:
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />

other wise there will be no Content-Type.

according to the php documentation:

getallheaders -- Fetch all HTTP request headers

those are the ones i need. the "request" headers that the client sends to the server... so if the client requests html, wap, hdml or whatever... i'll know what to send back...

anyway i just tried apache_response_headers() and i got the same error... do i need some sort of global tags in the php.ini somewhere?

Not that i'm aware of, but run this:

echo phpversion();

let me know the result.

my php is 4.2.3...

apache_response_headers() was only created in 4.3.0 same with apache_request_headers() but apache_request_headers() is called getallheaders() in versions below 4.3.0 and does the same thing.

The reason why your not getting anything when you do:

$moo = getallheaders();

echo $foo = $moo["Content-type"];

is cause the key from the array $moo doesn't exist.

Try echoing out the array to see if it does exist and remember it's case sensitive.

If nothing comes out at all most likely your php is not loaded as an apache module.
