concatinating two array elements with a string within a foreach loop

Question

I am trying to combine two array elements with the string "OR" and create one string of elements.

The array looks like this: $myarray = array(2282396,1801345)

This is the code i have used.

$bool = ' OR ';
foreach($myarray as $element){

echo $element .= $bool;
}

I trying to get this output after looping using a foreach loop. 2282396 OR 1801345

However, the output i get looks like this: 2282396 OR 1801345 OR

How do i get rid of the 'OR' after the second element? Thanks in advance

You have to check if you're in the first/last iteration or not.

$first = true;
$bool = ' OR ';
foreach ($myarray as $element) {
    if (!$first) {
        echo $bool;
    }
    echo $element; 
    $first = false;
}

If your array is indexed by numeric indexes 0-x, you an use

$bool = ' OR ';
foreach ($myarray as $key => $element) {
    if ($key > 0) {
        echo $bool;
    }
    echo $element; 
}

@dWinder: sure, I know. The OP asks for foreach loop. It can be simplified code in question, probably doesn't need to use just echo, etc. The OP asks for the foreach loop, so there is an answer with foreach loop.

Works like a charm @panther. I am accepting this as an answer

I don't think the OP knew what he wants - this is our job to not just answer him but also to teach him - as sometime he doesn't know what he need

Use implode as:

echo implode(" OR ", $myarray);
