How I Can Make A Loop From The Values Of An Object?

[giwrgos]

Hello everyone. i'm new on this site and also new on PHP coding. I want to make a loop using the values of an object (name of the object is test). my object has categoryid,parentid and i want to make something like this

 

forearch(categoryid){

foreach(parentid){

 

if (parentid == categoryid){

do something

}

}

}

 

Can anyone help me to do this loop?

Thank you

foreach works on arrays and objects. If your object has an array called categoryid, you can use foreach on it. Otherwise, you need to explain what you're trying to do. You can't foreach on a single value.

Im using PDO where i'm getting values from the database as an object "setFetchMode(PDO::FETCH_OBJ)"

Then i return this values in the test variable and i want to make a foreach loop for any of the files that the test has.

 

for example i can make foreach (test->categoryid as $categoryvalue) ?

Did you try it?

 

You're still not making sense. Is categoryid an array? If so, it should probably have a better name, but if not, why would you WANT to loop through it?

categoryid is a field. if a make this loop

 

fooreach ($test as $row){

echo $row->categoryid;

}

it will print all the values of the field categoryid

foreach($thingYouAreTryingToDo as $someQuestion){
foreach($someQuestion as $question => $answer){
if($question == 'makes no sense'){
$answer = 'impossible to give';
}
}
}

 

Jassica has already asked you to provide an explination as your question, as it stands, makes no sense.
