PHP - accesing to data of multi-dimensional array - php

Question

I am trying to access data in a multi-dimenstional array.
I need to get values of this data (EC000001, EG000017, EN, EF007220) but I am struggling with foreach loops in PHP, especially when need to nested foreach Could you please help me and give me solution to access wanted data?
I need to loop over all $c's and then loop inside to get all needed data.This is how I collected value EC000001 before, but I believe that there is a better solution.
foreach ($c as $classCodes => $value) {
$classCode = key($c[$classCodes]); //classCode -> EC000001
}
Structure of array:
Array
(
**[EC000001]** => Array
(
[0] => **EG000017**
[1] => Array
(
[0] => Array
(
[0] => **EN**
[1] => Busbar terminal
)
[1] => Array
(
[0] => **nl-NL**
[1] => Aansluitklem stroomrail
)
)
[2] => Array
(
[0] => Array
(
[0] => **EF007220**
[1] => EU570448
[2] => Array
(
)
)
[1] => Array
(
[0] => EF007219
[1] => EU570448
[2] => Array

)
[2] => Array
(
[0] => EF000073
[1] =>
[2] => Array
(
[0] => EV009241
[1] => EV009472
)
)
[3] => Array

Answer 1

I can not test it, but you can try with this inside the loop:
$value[0]; // -> 1
$value[1][0][0]; // -> 2
$value[1][1][1]; // -> 3

Answer 2

$EG000002Array[0][EG000001][0]
$EG000002Array[0][EG000001][1][0]
$EG000002Array[0][EG000001][1][1][1]

Answer 3

there are many ways to get array values from multi dimensional array
for example using foreach():
$flavors = array('Japanese' => array('hot' => 'wasabi',
'salty' => 'soy sauce'),
'Chinese' => array('hot' => 'mustard',
'pepper-salty' => 'prickly ash'));
// $culture is the key and $culture_flavors is the value (an array)
foreach ($flavors as $culture => $culture_flavors) {
// $flavor is the key and $example is the value
foreach ($culture_flavors as $flavor => $example) {
print "A $culture $flavor flavor is $example.\n";
}
}
or using for( ) :
$specials = array( array('Chestnut Bun', 'Walnut Bun', 'Peanut Bun'),
array('Chestnut Salad','Walnut Salad', 'Peanut Salad') );
// $num_specials is 2: the number of elements in the first dimension of $specials
for ($i = 0, $num_specials = count($specials); $i < $num_specials; $i++) {
// $num_sub is 3: the number of elements in each sub-array
for ($m = 0, $num_sub = count($specials[$i]); $m < $num_sub; $m++) {
print "Element [$i][$m] is " . $specials[$i][$m] . "\n";
}
}
the output should be like :
Element [0][0] is Chestnut Bun
Element [0][1] is Walnut Bun
Element [0][2] is Peanut Bun
Element [1][0] is Chestnut Salad
Element [1][1] is Walnut Salad
Element [1][2] is Peanut Salad

You can use recursion and regex to check if it's bolded :)
Notice we put& to $classCodes to pass it by reference and not
by value.
Function:
function get_bolded_data($c, &$classCodes = array()){
foreach($c as $k1 => $v1){
if(is_array($v1)){
//If $v1 is an array we call get_bolded_data() again and pass
//$v1 and $classCode
get_bolded_data($v1,$classCodes);
}else if(preg_match("/(\*\*).*(\*\*)/", $v1)){
$classCodes[] = $v1;
}
}
}
Usage:
$classCodes = array();
$c = array(
0 => array(
'**EC000001**' => array(
0 => '**EG000017**',
1 => array(
0 => array(
0 => '**EN**',
1 => 'Busbar terminal'
) ,
1 => array(
0 => '**nl-NL**',
1 => 'Aansluitklem stroomrail'
)
) ,
2 => array(
0 => array(
0 => '**EF007220**',
1 => 'EU570448',
2 => array()
) ,
1 => array(
0 => 'EF007219',
1 => 'EU570448',
2 => array()
) ,
2 => array(
0 => 'EF000073',
1 => '',
2 => array(
0 => 'EV009241',
1 => 'EV009472'
)
) ,
3 => array(
0 => 'EF007092',
1 => 'EU570448'
) ,
4 => array(
0 => 'EF004969',
1 => 'EU570126'
)
)
)
)
);
//Call our function
get_bolded_data($c, $classCodes);
Here is the result from var_dump:
array(4) {
[0]=>
string(12) "**EG000017**"
[1]=>
string(6) "**EN**"
[2]=>
string(9) "**nl-NL**"
[3]=>
string(12) "**EF007220**"
}
