Update key value in array of objects php

Question

I have an array of objects where the reference is not the same as the code_cip.

Array ( 
[9921279] => lignecatalogue Object ( [id] => 3013181 [reference] => 9921279 [commentaire] => [code_cip] => 9884064 )
[9884064] => lignecatalogue Object ( [id] => 3013193 [reference] => 9884064 [commentaire] => [code_cip] => 9884064 )
)

What i am trying to accomplish is to update only the [reference] => 9921279 on the first item to [reference] => 9884064. The [reference] will be updated only if it is not equal to its code_cip. So far i am stuck on the code below.

$arrLigneCats = getAllCat(); //returns above array

foreach($arrLigneCats as $ligneCat) {
    if ($ligneCat->code_cip != $ligneCat->reference) {
        $reference = $ligneCat->reference;
    } else {
        $reference = $ligneCat->code_cip;
    }
}

Anyone has any idea of how to replace the key without the removing the entire line?

Problem! Should you also be amending the key as well as that seems to match the reference — RiggsFolly

Pass the $ligneCat by reference, like this foreach($arrLigneCats as &$ligneCat) { — RiggsFolly

If I have understood your question correctly, the problem is that $reference is just a variable, what you have to change is the reference property of the object. So it will be:

$arrLigneCats = getAllCat(); //returns above array

foreach($arrLigneCats as $ligneCat) {
    if ($ligneCat->code_cip != $ligneCat->reference) {
        $ligneCat->reference = $ligneCat->code_cip;
    }
}

Does it answer your question?
