echoing out two dimensional associative arrays in php - php

Question

I would like the data to be echoed out in this format
[0] - [name][description]
[1] - [name][description]
[2] - [name][description]
$options = array('guide_info' => $guide_info);
$guide_info = array( 'guide_name' => $guide_name,
'guide_description' => $guide_description
);
I created two foreach loops to try and echo out the name and description of each, like this:
foreach ($options as $key => $value) {
foreach ($guide_info as $type => $info){
$html .= $type . " " . $info . "\n";
}
}
but I receive errors about invalid argument supplied for foreach() on the second loop.
Currently my print_r($options) shows
Array ( [guide_name] => f
[guide_description] => fff
[0] => Array (
[guide_name] => fsss
[guide_description] => sssss
)
)
and my echo prints
guide_name fsss
guide_description sssss
guide_name fsss
guide_description sssss
guide_name fsss
guide_description sssss
How would I be able to echo out the correct information that print_r is showing?

Answer 1

Use a recursive function to echo out the name and description values in the desired format.
function process_array($arr, $counter){
foreach($arr as $key => $value){
if(is_array($value)){
process_array($value, ++$counter);
}else{
if($key == "guide_name"){
echo "[" . $counter . "] - [" . $value . "][";
}else{
echo $value . "]<br />";
}
}
}
}
// Here $options is your original array
process_array($options, 0);
Output:
[0] - [f][fff]
[1] - [fsss][sssss]

Answer 2

$guide_info = array( 'guide_name' => 'guid name',
'guide_description' => 'guid description',
);
$options = array('guide_info' => $guide_info);
foreach ($options as $key => $value) {
foreach($value as $a => $b) {
echo $a," =",$b ;
}
}
or for print_r
foreach ($options as $key => $value) {
print_r($value) ;
}

Why are you putting the $guide_info in $options.If you want all the entries from $guide_info, you can do this-
for($i = 0; $i < count($guide_info); $i++){
$html .= $type . " " . $info . "\n";
}
-> considering $guide_info is a multidimensional array like = array( [0] => 'guide_name' => $guide_name,
'guide_description' => $guide_description)
If for some reason $guide_info IS important, I would suggest it to be an indexed array not assoc.. Hope you find the solution :)
