Variable Array Name in foreach

[farrell.niall@gmail.com]

Hi,
I'm trying to use nested foreach loops to loop through two arrays.
Each element in the first array corresponds to another array. The
brandcode part of the first array is the same as the name of the
corresponding array.
Basically, one array is of the brand info, and the second is of the
cars made by that brand.
To loop through all the brands, and then print their corresponding
cars, I tried:
foreach ($brands as $curbrand) {
foreach (${$curbrand['brandcode']} as $curcar) {
echo $curcar;
}
}
But I get "Invalid argument supplied for foreach()"
Any ideas?

Re: Variable Array Name in foreach

This should work for you...

foreach ($brands as $curbrand) {
foreach ($curbrand as $brandcode =$curcar) {
echo $curcar;
}
}

the syntax above in the inner loop is for when you have key value
pairs in the array of interest.

so that line could be rewritten, foreach($curbra nd as $key =$value)

Hopefully this is what you are looking for.

It's clearly not what the OP is looking for.

No, that didn't do it but thanks anyway. I figured it out eventually -
this seems to do the trick:
foreach ($brands as $curbrand) {
$cars = ${$curbrand[brandcode]};
echo $curbrand[brandname];
foreach ($cars as $curcar) {
echo $curcar;
}
}
It basically echoes the brandname followed by all the cars in the
array of the same name. $cars = ${$curbrand[brandcode]} was the main
bit I was looking for - assigning a variable as the array name.

I am not 100% sure I have understood your problem but the following works
for the way I envisaged your arrays:-

$brands = array('porsche' , 'ford');
$porsche = array('911');
$ford = array('escort') ;
foreach ($brands as $r)
{
foreach (${$r} as $model)
{
echo $model;
}
}

The error you have suggests that you are not passing an array to the foreach
loop instead you are passing a value.

I love it when people state this, and fail to provide an explanation, let
alone state what, according to them, is a correct answer to what the OP is
looking for.
