php foreach loop display all data

I have dump problem with foreach loop... I want to display all data in foreach, example:

$data[1] = "Hello"; 
$data[2] = "my"; 
$data[3] = "World";

I use this script and work

for($i=1; $i<3; $i++){
        $mydata = $data[$i];
        echo $mydata; }

This is ok, no problem. But when I want to include $mydata in next script (for saving in txt), he shows only the last word, World

Why? How to include all data from variable

You have just echoed $mydata inside for loop so it will print the value as of last occurrence value as you are changing/overriding the $mydata variable value.

Use like this:

$mydata = '';//Storing $mydata variable
for($i=1; $i<3; $i++){
  $mydata .= $data[$i]; //adding up the values to $mydata
}
var_dump($mydata); //dumps all the $data value.

Every time you are overwriting the variable $mydata and your are print that one so it replacing each time, you can store that into array and dump that variable after loop ended, 

for($i=1; $i<3; $i++){
    $mydata[] = $data[$i];
    echo $data[$i]; 
}

echo '<pre>';
print_r($mydata)

# You can directly dump the all the variable as follow
echo implode('\n', $mydate) 
# or
echo implode('\n', data)

Try this : 

$mydata = '';
for($i=1; $i<3; $i++){
   $mydata .= $data[$i];
}
echo $mydata;
