I have an array
Array
(
[0] => Array
(
[proomsize] => dasfdsfdsf
[proomtype] => Bedroom
)
[1] => Array
(
[proomsize] => dasfdsfsd
[proomtype] => Bedroom
)
[2] => Array
(
[proomsize] => dfadsf
[proomtype] => KitchenDinner
)
[4] => Array
(
[proomsize] => dafdsads
[proomtype] => Reception
)
[5] => Array
(
[proomsize] => fdsafdsfdsf
[proomtype] => Reception
)
[6] => Array
(
[proomsize] => adfadfdsf
[proomtype] => Reception
)
)
Now i need is if there is more than one $array['proomtype'] of same value i want to append a number at the end in my foreach loop.. so when i loop through it i want a result like this
Bedroom 1 : dasfdsfdsf
Bedroom 2 : dasfdsfsd
KitchenDinner : dfadsf
Reception 1 : dasfdsfsd
Reception 2 : adfdsf
Reception 3 : dfdfdf
how can i achieve that in a single loop i have tried using this
<?php
$BedroomCounter = 0;
if ($value['proomtype'] == 'Bedroom') {
if ($BedroomCounter == 0) {
echo $value['proomtype'] ':' .$value['proomsize'] . '<br>';
}else{
echo $value['proomtype'] . $BedroomCounter . ':' .$value['proomsize'] . '<br>';
}
$BedroomCounter++;
}
the issue is i have repeat this for each n every roomtype.. which is not something i want to.
The way this works is by first using array_count_values()
to count the number of each type of room, this helps know when we need to add a suffix or not.
It then creates a copy of this array with the current counter for each room type starting at 1 using array_fill_keys()
.
The code then loops through all of the entries looking up the room type and if the room type has more than 1 entry it adds the suffix from the counter array and increments that counter.
$duplicates = array_count_values(array_column($value, "proomtype"));
$currentCount = array_fill_keys(array_keys($duplicates), 1);
foreach ( $value as $key=>$entry ){
if ( $duplicates[$entry["proomtype"]] > 1 ) {
$value[$key]["proomtype"] .= " ".$currentCount[$entry["proomtype"]];
$currentCount[$entry["proomtype"]]++;
}
}
print_r($value);
The output with your example data is...
Array
(
[0] => Array
(
[proomsize] => dasfdsfdsf
[proomtype] => Bedroom 1
)
[1] => Array
(
[proomsize] => dasfdsfsd
[proomtype] => Bedroom 2
)
[2] => Array
(
[proomsize] => dfadsf
[proomtype] => KitchenDinner
)
[4] => Array
(
[proomsize] => dafdsads
[proomtype] => Reception 1
)
[5] => Array
(
[proomsize] => fdsafdsfdsf
[proomtype] => Reception 2
)
[6] => Array
(
[proomsize] => adfadfdsf
[proomtype] => Reception 3
)
)
