create a string variable with all of an array's items [duplicate]

Question

I'd like to create a string variable from an array.

Here's a non working code for conceptualizing it:

$list = array('elem1', 'elem2', 'elem3', 'elem4');

$myString = foreach ( $list as $element ){
    '<span>' . $element . '</span><span>|</span>';
};

Answer 1

You can do something like this

 <?php
    $lists = array("elem1", "elem2", "elem3", "elem4");
    $string = '';
    
    foreach ($lists as $element){
        $string = $string . ' | '. $element;
    };
      
    echo '<span>' . $string . '</span>';
    ?>

Answer 2

$list = array('elem1', 'elem2', 'elem3', 'elem4');

foreach( $list as $element ){
    $myString[] = '<span>' . $element . '</span><span>|</span>';
}

print(implode('', $myString));

Answer 3

What you could do is concatenate the results of each iteration of your loop to a variable that exists outside of the loop.

Example:

$list = array('elem1', 'elem2', 'elem3', 'elem4');

$myString = '';
foreach ( $list as $element ){
   $myString .= $myString . '<span>' . $element . '</span><span>|</span>';
};

print($myString);
