Joinging the list to string

[siva1740]

Given a list a = ['a', 'b', 'c', 'd'] and an empty string s = '', how can I use a for-each loop to add each element of the list to s so that it stores the result as s = 'abcd'? Should I use add or push?

The simplest way is to use the implode

$a = ['a', 'b', 'c', 'd'];
$s = implode('', $a);
echo $s; // 'abcd'

$a = ['a', 'b', 'c', 'd'];
$s = join('', $a);
echo $s; // 'abcd'

join is an alias for implode, so it works the same way.
