[SOLVED] Quick help regarding variable name

[play_]

Hi again.

 

I have a for() loop, where $i increments to 10.

 

Inside the loop, i wanna create a variable(say $var_);, with $i appended at the end.

So everytime the loop goes around, i'd get $var_1, $var_2, $var_3.........$var_10.

 

doing $var_$i = 'string' doesn't work.

i dont get it but are you referring with concatenation then use the dot .

after another variable

[redarrow]

$var[$i]

dont know what u need that for but there are arrays for that m8

 

$var = array();
for($i=1; $i<=10; $i++){
$var[$i] = 'string'; //it will asign to $var[1] - $var[10] the value 'string'
}

I am concatenating, but not to output. I wanna concatenate to create a variable

 

here's my code

 

for($i = 0; $i <= 10; $i++) {
        // i wanna do something like this.  So it would create 10 variables. $var_0, $var_1, $var_2....etc
$var_ $i = "some string";

}
}
?>

The problem is it can't be an array. Guess i should've mentioned that 

[tippy_102]

new_variable = "var_" . '$i';

 

???

[BlueSkyIS]

and then you can refer to it as a variable:

 

${"var_" . $i}

Thanks tippy, but that wouldn't work =)

Use:

$i = 10;

$var_10 = 'hello';

echo ${'var_' . $i};

 

EDIT Beaten to it by tippy, But anyways if you want to use variables value as part of a variables name you'll have to use variable variables, which what the above is

[Barand]

<?php
for ($i=1 ; $i <= 10 ; $i++)
{
    $varname = "var_$i";
    $$varname = $i;
}

echo $var_5;             // --> 5
?>

 

As said, I can't see why anyone would want to do this now the array has been invented.

Couldn't i do ${'var_'.$i} =  'string' ?

[play_]

<?php
for ($i=1 ; $i <= 10 ; $i++)
{
    $varname = "var_$i";
    $$varname = $i;
}

echo $var_5;             // --> 5
?>

 

As said, I can't see why anyone would want to do this now the array has been invented.

 

I already have a multidimensional array(3 arrays nesting). don't want more though.

[play_]

Yes that worked.

<?php
$form = array();
for($i = 0; $i <= 10; $i++) {
if(!empty($_POST["option_$i"])) {
	${'row_'.$i} = array();
	$form[] = ${'row_'.$i};
	print_r($form);
}
}
?>

 

 

Thanks eeeeeveryone.
