Array

[Nickosssss]

hello there

i have an array. for example 115, 115, 117, 118, 118

how can i compare the values in it....the values each time of execution will change so i cant use in_array because i wont know the values....Moreover tthis array is a result from a mysql query.

$len = count($topic);

for ($i = 0; $i < $len; $i++)
{
for ($j = 1; $j < $len; $j++)
{
if ($topic[$i] == $topic[$j])
{

		echo 'yes';

	}
	else
	{
		echo 'no';

	}

}

}

i am using tthis so far but how can i isolate 117 which appears only once?

thank u

Logically, if you dont know what you're searching for, you wont find it.
You might not know what you're searching for before you know it, but once you know it, you might be able to find it.

Okay, enough of the philosophy 🙂
You can still use in_array() since you would have the value to search for at some point - not at the time of writing of the script, but in some variable, in this case a variable storing certain data from your database.

the main point it to detect those values that do appear more than one time....

if they appear > 1 then do something.....

if not then do something else...

so u mean to store a value and then try to see if its in the array?

Actually, [man]array_count_values/man may be easier here.
