Re: [PHP] Comma question

2002-07-22 Thread Evan Nemerson 

The comma just concatenates the two. The brackets don't seem to do much of 
anything...

echo trtd$strName/td/tr.htmlspecialchars( $teststr );

seems to be the same...

Re: [PHP] Comma question

Curly braces {} are sometimes required for PHP to properly parse variables
within quoted strings.  Good example might be defining variable-variables
within a quoted string  ${$myvarvar}.  However I do not believe that curly
braces are required in this particular string.

As for the comma I believe it does the same thing as the period.  It will
concatonate the quoted string with the output of the htmlspecialchars()
function within the echo statement.

 What does the , and {} do in this type of statement?

 Example:  echo trtd{$strName}/td/tr, htmlspecialchars(
$teststr );

 Thanks,

Re: [PHP] Comma question

Thanks all for the info...

I figured that the comma was to concatenate but is was wondering if the
parser handled it different.

I knew the {} helped the parser now which was the variable...but i have
never seen it like that...

I have only seen it like ${var}...

Just wondering the difference...

RE: [PHP] Comma question

2002-07-22 Thread Martin Towell 

I remember from a previous post, the dot operator will create a temporary
string in memory, and then echo that out. The comma operator will just
output as it goes - ie. it doesn't create a temporary string.


As for Lee Doolan's reply:
  echo trtd{$obj-strName[$i]}/td/tr;
interesting - never thought of doing that, I alway's broke out of the quotes
to do object dereferencing. Should make my future code more readable I
think...

Not sure about the comma, but the {braces} are easy.  They help separate the
$vars from other stuff in the string.

Example:

?
$string =  something ;
echo This will$somethingprobably not work;
echo This will{$something}probably not work;
?

It's a good habbit to get into, and has saved my arse on a few occasions,
although the above example isn't a good one.

The comma isn't actually for concatenation. The net effect is the same in 
this case, but a very different thing is happening.

  echo hello  , there;

Here 'echo' is printing two separate arguments. First it is printing 
hello  and then it is printing there.

  echo hello  . there;

Here the strings are concatenated to form a single string (hello there) 
and then this is processed by echo which prints it out.

The effects are the same, as I said, but it's important to realize why 
they're very different ways of getting that effect.
