How to auto increment in sub foreach loop? - php

Question

Here is the example code:
<?php
$arr = array(
array(
'company' => array(
'code' => 'ccd1',
'name' => 'cnm1'
) ,
'products' => array(
array(
'code' => 'pcd1',
'name' => 'pnm1'
) ,
array(
'code' => 'pcd2',
'name' => 'pnm2'
)
)
) ,
array(
'company' => array(
'code' => 'ccd2',
'name' => 'cnm2'
) ,
'products' => array(
array(
'code' => 'pcd1',
'name' => 'pnm1'
) ,
array(
'code' => 'pcd2',
'name' => 'pnm2'
) ,
array(
'code' => 'pcd3',
'name' => 'pnm3'
)
)
)
);
echo "<pre>"; print_r($arr); echo "</pre>";
$AI = 1;
foreach($arr as $value){
$total_products = count($value['products']);
echo $AI++.".{$value['company']['name']} ({$total_products})<br />";
foreach($value['products'] as $value2){
echo " ".$value2['name']."<br />";
}
}
I don't know how to explain it, but what I want is to add auto increment in sub foreach loop, like this:
1.cnm1 (2)
1.pnm1
2.pnm2
2.cnm2 (3)
1.pnm1
2.pnm2
3.pnm3

Answer 1

Usually you can just use the foreach keys plus one. As another alternative, if this is just for presentation, just use ordered lists:
echo '<ol>';
foreach($arr as $ar1) {
echo '<li>' . $ar1['company']['name'] . ' (' . count($ar1['products']) . ')</li>';
echo '<ol>';
foreach($ar1['products'] as $ar2) {
echo "<li>{$ar2['name']}</li>";
}
echo '</ol>';
}
It'll number those items accordingly. No need for addition. Plus you can use CSS to style the list,

Answer 2

You can access the key/index of an foreach :
foreach($arr as $i => $value){
$total_products = count($value['products']);
echo ($i+1).'.'.$value['company']['name'].' ('.$total_products .')<br />';
foreach($value['products'] as $j => $value2){
echo ' '.($j+1).'.'.$value2['name'].'<br />';
}
}

Answer 3

Here you go.
$arr = array(array('company'=>array('code'=>'ccd1', 'name'=>'cnm1'), 'products'=>array(array('code'=>'pcd1', 'name'=>'pnm1'), array('code'=>'pcd2', 'name'=>'pnm2'))), array('company'=>array('code'=>'ccd2', 'name'=>'cnm2'), 'products'=>array(array('code'=>'pcd1', 'name'=>'pnm1'), array('code'=>'pcd2', 'name'=>'pnm2'), array('code'=>'pcd3', 'name'=>'pnm3'))));
echo "<pre>";
print_r($arr);
echo "</pre>";
$AI = 1;
foreach($arr as $value)
{
$total_products = count($value['products']);
echo $AI++.".{$value['company']['name']} ({$total_products})<br />";
$k = 0;
foreach($value['products'] as $value2)
{
echo " ".$k++.". ".$value2['name']."<br />";
}
}

Answer 4

This also worked for me:
foreach($value['products'] as $key2=>$value2){
$AI2 = $key2+1;
echo " ".$AI2.".{$value2['name']}<br />";
}

Answer 5

You can try this:
foreach($arr as $value){
$total_products = count($value['products']);
echo $AI++.".{$value['company']['name']} ({$total_products})<br />";
$sub=1;
foreach($value['products'] as $value2){
echo " ".$sub++.'.'.$value2['name']."<br />";
}
}
