Creating a loop

[senyo]

I am trying to create a loop in a big script. But I don't know what to do. I have an array, I take every value from it. I managed to make a if to compare the values, but I don't know what to write in it. If the values are equal then it should take $array[2] and compare it $gor[some]. How I make it to loop?

 

      if ($array[1]= $gor[some])
{
//how to loop, how to make it compare $array[2] with $gor[some]
}

else
{
echo "x is smaller than y";
}

are you just trying to find out if $gor[some] is in $array?

 

can you explain what the end goal of the loop will be?

 

There are several ways easy to loop through that array, but each can have a different end result.

This is what I want to do:

 

I have an array with different values, I take them one by one $array[1], $array[2] etc to compare them with $gor[some] that is taken from a DB, if $array[1]==$gor[some] then it must go back and compare $array[2] and so on. If the values are not equal then the loop for this array[something] ends and continues the script. But the loop should continue comparing the next array array[something1] with $gor[some]

Ok .. so if understand right, you don't really have to use a loop for this although you could.

 

you can use

http://us2.php.net/manual/en/function.array-keys.php

 

array_keys() but you need to put the optional param in.

 

it would look something like this.

 

$locationInArray = array_keys($array,$gor[some]);
//this will return all the keys in the array that match $gor[some]

 

I am still a bit unclear about what you want to have happen after the comparison is finished, but that could be my fault, it is quite early in the morning here

I will write each condition manually, thanks

[severndigital]

ok ... bear with me ..now i am confused.

 

are you matching $gor[some] to mutiple arrays?

 

 

[senyo]

Yes

[severndigital]

ok .. that's a bit different that your first question.

 

I have an array with different values...

 

how are the arrays getting into this script? if they are separate arrays you will have to hard code each loop for each array.

Hello senyo,

 

What you are trying to do here i am not getting properly. Is that both the arrays are coming (fetched) from the database? are you running any query and getting both the arrays?

 

or you want to do something like this

 

$a = array('a', 'b');
$b = array('a', 'c');

$r1 = array_compare($b, $a); // false
$r2 = array_compare($b, $a, false); // true 

 

Could you please be more specific so we will get the idea what you want to do exactly.

[senyo]

both arrays are fetched and I want to compare an array with the content of another array

[severndigital]

are you sure .... according to your first question you want to compare and array to a value

 

which question are you trying to answer?

is the value of $gor[some] in the array $array

or

does $array have the same values in it as the array $gor?

 

 

 

[senyo]

I want to compare the value of an array, with a value from an array

[deepson2]

Try this-

 

$matches = array_intersect($array1,$array2);
if (count($matches) > 0)
{
// matches found so do you stuff.
print_r($matches); // print the matches just to check.
}

 

Still i am not sure about what you are doing. could you please post your code snippet so we can get some idea what are you doing.
