How do I concatenate each the values of a variable1 with each values of variable2

// a simpler thing that would get me what I need is: How do I concatenate each the values of a variable1 with each values of variable2

$Var1 = 'my1, my2, my3'; // here I have dozens of entries, they are    symbols
$Var2 = 'word1, word2, word3'; // here also dozens of entries, are words.

How do I have all the keys of a variable, placed together of the keys of another variable?

$Values_that_I_needed = 'my1word1, my1word2, my1word3, my2word1, my2word2, my2word3, my3word1, my3word2, my3word3';

How would I build this values this variable up with all those values without having to type everything!?

Imagine an example with 60 my1, my2 … and 130 word1, word2 …. it’s my case! Put each of the 60my before each of the 130 words !! // I need to concatenate / join / join each values / keys of a variable, with all the values/keys of another variable, to avoid making all these combinations by hand. and put in another variable.

The solution using explode and trim functions:

$Var1 = 'my1, my2, my3'; // here I have dozens of entries, they are    symbols
$Var2 = 'word1, word2, word3';
$result = "";
$var2_list = explode(',', $Var2);

foreach (explode(',', $Var1) as $w1) {
    foreach ($var2_list as $w2) {
        $result .= trim($w1) . trim($w2). ', ';
    }
}
$result = trim($result, ', ');
print_r($result);

The output:

my1word1, my1word2, my1word3, my2word1, my2word2, my2word3, my3word1, my3word2, my3word3

$Var1 = 'my1, my2, my3';
$Var2 = 'word1, word2, word3';

$Array1 = explode(", ",$Var1); // create array from $Var1
$Array2 = explode(", ",$Var2); // create array from $Var2

foreach($Array1 as $My){
    foreach($Array2 as $Word){
        $Result[] = $My.$Word; // Join Var1 & Var2
    }
}
$Values_that_I_needed = implode(", ", $Result); 
echo $Values_that_I_needed; // my1word1, my1word2, my1word3, my2word1, my2word2, my2word3, my3word1, my3word2, my3word3

Below cod should work if var1 and var2 have the same length

<?php
$tab1=explode(',',$var1);
$tab2=explode(',',$var2);

$c=$count($tab1);
$output='';
for($i=0;$i<$c;$i++){
$output.=$tab1[$i].$tab2[$i].', ';
}
echo $output;
