dynamic array name

[smagdy]

hi,

How to create PHP array with dynamic name?

thanks

[jatar_k]

well it is a very vague question but I have always used variable variables [php.net]

$a = 'apple';
$num = '5';

${$a . $num} = array('one','two','three');

echo '<pre>';
print_r($apple5);
echo '<pre>';

make any sense at all?

yeah makes sense but i wouldnt figure out this:

${$a . $num} = array(...)

but thanks ill try it.

the thing that makes it hard is I don't know what you are creating the array name dynamically from.

I use it for all sorts of things.

Mostly when I don't know how many of something there will be so I use a counter to create the vars. ending up with var1, var2, var3, etc. I can then loop through, or just use, them later no matter how many there end up being.

Sorry am still confused.

how to insert some value in the array after the initializing and also how to echo whats inside the array?

[smagdy]

Please look at this:

$getDose=0;

$a = 'comp';
$$a=$getDose; //This create variable $comp=0.

$a.${$a} = array(); //This create array named comp0
$a.${$a}[0]="sherif"; //This put "sherif" in index[0]

hope what i am saying is right... so the problem now is i cant display what is at index[0].

i tried:
echo"$a.${$a}[0]";

it gave:
comp.Array[0]

so what should i do?

thanks in advance

try this

$getDose=0;
$a = 'comp';

${$a . $getDose}

this is constructing the variable name, it reads something like this

the variable who's name is the value of the variable a concatenated with the value of the variable getDose.

so..

${$a . $getDose} = array();
${$a . $getDose}[0] = 'sherif';

echo ${$a . $getDose}[0];

any better?
