How can I extract all elements from this array through PHP?
I tried to do with array_slice but it didn't help
My main problem is that I need to derive all the meanings, not just the last ones. So that it would be under different encodings that are contained in ['product'] - despite the fact that the keys for the arrays are the same
I don't know how to do it, please help, already broke my head

I would like to get about this
Symbol: CPLabel: Prohibition except under defined conditions
Code: 290377
Reported Code: ex 2903 77\u00a0600 0
Code: 290379
Reported Code: ex 2903 79\u00a0300 0
Symbol: NAL-X
Label: Non-automatic licensing
Code: 290377
Reported Code: ex 2903 77\u00a0600 0
Code: 290379
Reported Code: ex 2903 79\u00a0300 0
moreover, I return all this through return in one variable
i tried writing like this
$rbn = array_slice($dfs2['measures'], 1);
foreach ($rbn as $dfs4){
$jko4 = '<span style="color:#fff;">Label:</span> '.$dfs4['label'].'<br><span style="color:#fff;">Symbol:</span> '.$dfs4['symbol'].'';
foreach ($dfs4['products'] as $dfs5){
$jko3 = $dfs5['reported_description'];
}}
Initially, I had such a code
foreach ($dfs2['measures'] as $dfs4){
$jko4 = '<span style="color:#fff;">Label:</span> '.$dfs4['label'].'<br><span style="color:#fff;">Symbol:</span> '.$dfs4['symbol'].'';
foreach ($dfs4['products'] as $dfs5){
$jko3 = '<span style="color:#fff;">HS Version:</span> '.$dfs5['hs_version'].'<br><span style="color:#fff;">Code:</span> '.$dfs5['code'].'<br><span style="color:#fff;">Description:</span> '.$dfs5['description'].'<br><span style="color:#fff;">Reported Description:</span> '.$dfs5['reported_description'].'';
}}But in this version, it output the last element of the cycle (because each time it was overwritten), and it also output data only from the first array ignoring the second
CodePudding user response：
You may use the ob_start() and ob_get_clean() functions.
That way, you don't have to assign the HTML to variables, but you can output it the output buffer and then get the whole buffer in one return.
Your function would look something like this ( You can see how it works here ):
function get_measures( $data ) {
ob_start();
foreach ($data['measures'] as $dfs4){
echo '<div><span style="color:#fff;">Symbol:</span> '.$dfs4['symbol'].'</div>';
echo '<div><span style="color:#fff;">Label:</span> '.$dfs4['label'].'</div>';
foreach ($dfs4['products'] as $dfs5){
echo '<br />';
echo '<div><span style="color:#fff;">Code:</span> '.$dfs5['code'].'</div>';
echo '<div><span style="color:#fff;">Reported Code:</span> '.$dfs5['reported_code'].'</div>';
}
echo '<br /><br />';
}
return ob_get_clean();
}
There are some other things that can be done to this code to be better, but it's off the scope of this question.
