Update key value in array of objects php-CodePudding

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?

CodePudding user response：

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?
