Unwanted newline php

[ryan fitzer]

I'm writing a command using php that reorders a css property list by
string length. The problem I'm having is that a newline character is
being added at the beginning of the result for some reason (using
Replace selected text). I've consulted this thread
http://lists.macromates.com/textmate/2007-April/019068.html but I've
found no way of echoing a string without the newline being added. Here
is the command:

#!/usr/bin/php

<?php

$fstat = fstat(STDIN);
$stdin = fread(STDIN, $fstat['size']);

//print_r($stdin);

$pattern = '/\{(.*)\}/Us';
preg_match($pattern, $stdin, $matches);
$output = trim($matches[1], "\n");
$output = preg_split('/\n/', $output);

function sort_strlength($val_1, $val_2) {
        // initialize the return value to zero
        $retVal = 0;

        // compare lengths
        $firstVal = strlen($val_1);
        $secondVal = strlen($val_2);

        if($firstVal > $secondVal) {
                $retVal = 1;
        } else if($firstVal < $secondVal) {
                $retVal = -1;
        }
       
        return $retVal;
}

uasort($output, "sort_strlength");

$out = '{' . "\n";
foreach($output as $line) {
        $out .= $line . "\n";
}
$out .= '}';

print(trim($out));

?>

Any help would be appreciated.

You just need to remove the newline between

> #!/usr/bin/php
and
> <?php

Holy cow! I can't believe I missed that. Of course, I new to server
side languages. Thanks so much for the help.

Here is the updated command for those interested (a little more efficient)

-----------------------
#!/usr/bin/php
<?php

$fstat = fstat(STDIN);
$stdin = fread(STDIN, $fstat['size']);

$pattern = '/\{(.*)\}/Us';
preg_match($pattern, $stdin, $matches);
$match = trim($matches[1], "\n");
$match = preg_split('/\n/', $match);

$properties = array();

foreach($match as $line) {
        $properties[strlen($line)] = $line;
}

ksort($properties);

$output = '{' . "\n";
foreach($properties as $line) {
        $output .= $line . "\n";
}
$output .= '}';

echo(trim($output));

?>

Just remember that PHP will treat everything outside of <?php ?> as part of a document and blindly output it.

This has bitten many people when they try to send a Content-type header and get errors because their script started with blank lines and/or comments, which causes most web servers to start sending it as “text/html” automatically.

I am surprised this works. STDIN is a pipe and can’t be stat’ed for
file size.

I would suggest instead using file_get_contents("php://stdin").
