[PHP] Re: Dynamic constant names -SOLVED

[Art Wells]

My apologies for assuming too much of the variable names.  Thank you for
correcting me.

Your response has caused me good confusion though.  If I remove the ${...}
notation I get quite a different output (specifically, there's no output).
Are you sure the parser ignores it?

This is the code I suggested WITHOUT the ${...} that returns nothing.
$test_name="ta_dah";
define("constant_name","test_name");
$constant_value=$constant_name;
echo $constant_value;

And I wonder too if my odd usage of ${...} notation is improper in
variables.  When I want to create a dynamically named variable (as opposed
to my off-topic constant example), I use:

${$variable_name}="value";
or even
${"fixed_string".$variable_name}="value";

I hope I'm not going against sane practices in doing so.

 Art,

 Thanks for the suggestion, but I think there is a flaw in your
 solution.

 The original issue was how to get at the value of a constant where the
 $constant_name is dynamically created as a variable.

 In your solution you have defined constant_name as a constant!
 So when you assign it, it does, of course, behave as a constant.

 I don't think the ${...} notation is doing anything - it is just being
 ignored by the parser so far as I can see ...

 AW $test_name="ta_dah";
 AW define("constant_name","test_name");
 AW $constant_value=${constant_name};

 Almost there... actually this creates one problem...

 It turns 40.00 into 4

 It needs to quit shaving zero's when it hits the decimal point.

 40.00 into 40
 45.50 into 45.5
 40.25 into 40.25

 Thanks

 ereg_replace("[0\.]*$", "", $number)

 should do it.  I'm not sure you need the slash in front of the dot or
 not. try it and see.

 In article
 [EMAIL PROTECTED] you
 write:
 I need to format decimals that are percise to the second place in the
 following format:
 
 4.00 to 4
 4.50 to 4.5
 4.25 to 4.25
 
 As you can see, I just want to drop the trailing zeros, and if necessary
 the
 decimal.
 
 Thanks

[PHP] Re: Fwd: Help - removal of trailing zeros from double integer field

[Art Wells]

This might help.

$no_trailing_zeroes = preg_replace("/0+$/","",$trailing_zeroes);


 Dear friends,

 I am accessing MySQL database using apache and php.
 I have to display a double integer field without trailing zeros.
 The number of digits after the decimal point varies.

 I have tried searching the archive and did not get any previous questions.

 Kindly help me in this regard.

 Thanking you.
