Storing and Retrieving Number String/Array

Jun 18th, 2008

I have a few number values that I need to store in one string/array and then use it at a later time.

The idea is:

 Help with Code Tags 
 PHP Syntax (Toggle Plain Text) 
$a = 1;
$b = 2;
$c = 3;
 
$alpha = $a + " " + $b + " " + $c;
 
echo $alpha;
$a = 1;
$b = 2;
$c = 3;

$alpha = $a + " " + $b + " " + $c;

echo $alpha;

The output of alpha in turn would be "6" I want it to be "1 2 3".

Also after it is stored possible to break it up again and then retrieve the values of "1 2 3" and store them back to new variables of $a1, $b1, $c1.

Thankyou, Regards X

to use them as string put quotations around them.

$a = '1';

then to break them up again use explode() function

if you are just trying to store some data just seperate the values using commas by i think using implode(do use it much) and use explode(",",$str); to get them out again.

echo $a1; //prints 1
echo $b1; //prints 2
echo $c1; //prints 3
?>

. is the concatenation operator not + !

Ignorance is definitely not bliss!

Nav to the rescue once again my hero!

Umm another thing will that work if the variables are double digits example 11, 22, 33 just the same for singular digits? Thanks

as long as they are spaced by the " " character, yes.

and if the number of values is unknown, you could also assign them directly to an array like so

 Help with Code Tags 
 PHP Syntax (Toggle Plain Text) 
$alpha = "11 22 33 44 55 66";
$array = explode(" ", $alpha);
 
/*
Then you will have
$array[0] = "11";
$array[1] = "22";
$array[2] = "33";
$array[3] = "44";
$array[4] = "55";
$array[5] = "66";
*/
 
//and you can loop through them like this
foreach($array as $value)
{
	echo $value . "<br />";
}
$alpha = "11 22 33 44 55 66";
$array = explode(" ", $alpha);

/*
Then you will have
$array[0] = "11";
$array[1] = "22";
$array[2] = "33";
$array[3] = "44";
$array[4] = "55";
$array[5] = "66";
*/

//and you can loop through them like this
foreach($array as $value)
{
	echo $value . "<br />";
}

Ok it worked but it didnt.

My small example did but when I changed it to my requirements I got this error:

 Help with Code Tags 
 PHP Syntax (Toggle Plain Text) 
Allowed memory size of 134217728 bytes exhausted (tried to allocate 10 bytes)
Allowed memory size of 134217728 bytes exhausted (tried to allocate 10 bytes)

Any idea on how I can fix this?
or will I need to program the above in java to work?
If so will it even work in java if it dosent work in php?

Thanks, Regards X
