[RESOLVED] str_pad() weird output

[peachP]

Can anyone suss why this code:

<?php
 $N='strOne';
 $L='strTwo';

 $N=str_pad($N,15,STR_PAD_RIGHT);
 echo($N.$L);
?>

produces this output:

strOne111111111strTwo

why is it padding with 1's instead of the default spaces ??

When i call str_pad with just the required args (string subject, padding length)
i.e.

]<?php
$N='strOne';
$L='strTwo';

$N=str_pad($N,15);
echo($N.$L);
?>

it produces this:

strOne strTwo

I thought it may be because i'm not using the third optional arg, pad_string so i included an extra pair of empty commas to denote its absence thus:

$N=str_pad($N,15,,STR_PAD_RIGHT);

This, though, generates an error pointing out the presence of the extra ',' in the str_pad() func

Its explained in the php manual as easy as falling off a log - yeah, in theory!!

Ofcource it give u error, how do u suggest php should interpret this ,, in your statement, when he's expacting a param...

Is it that hard to add your pad_string in there?

$N=str_pad($N,15,' ',STR_PAD_RIGHT);

Or even an empty string, if space is the default character ...

$N=str_pad($N,15,'',STR_PAD_RIGHT);

BTW, STR_PAD_RIGHT is a constant and the constant value is 1, that's why it give's u that value ...

[peachP]

Have u tested this code on your machine ?? .. tried on mine and it still produces an unpadded string.

Your point about STR_PAD_RIGHT, being a constant is recieved thanks for that But please don't reply with attitude, you may wish to read-up on netiquette.
forums work just fine without attitude - anonymity online has a lot to answer for!

peachP, I didn't see any attitude in his post. If you want results expect direct responses.

This code produces the desired output for me:

$one = str_pad("strOne", 15);
$two = "strTwo";

echo "{$one}{$two}";

Keep in mind that if you echo this to your browser without <PRE> tags it will not appear to have 15 spaces. View source to see the spaces.

Here is an easy way to convert those to browser-capable spaces:

$one = str_pad("strOne", 15);
$one = str_replace(" ", " ", $one);
$two = "strTwo";

echo "{$one}{$two}";

thanx for the solution m@tt,

I was obviously forgetting example in phpManual is outputting to a file, not HTML output

BTW:

echo "{$one}{$two}";

is new to me - does this save using the '.' concatenation operator or save using echo twice.

cheers again
( i still maintain that proper manners is good practice especially when comminicating anonymously) your reply had non of the att'ude that, bogu's had. It ain't just a girly thing i know bad manners when i hear it 🙂 )

That is merely a habit I picked up from another programmer for inputting variables into strings 🙂
