Required to convert arrays into strings Divided into two parts:

• Merge arrays: merge multiple arrays into one array

• Array to string: merge Convert the resulting array to a string

Implementation steps:

1. Use the array_merge() function to merge arrays

array_merge(array1,array2,array3...)You can merge two or more arrays. When the keys of the two arrays are the same, the value of the latter array overwrites the value of the previous array.

<?php
$a = [1,&#39;2&#39;=>2,&#39;a&#39;=>&#39;a&#39;,&#39;b&#39;=>&#39;b&#39;];
$b = [1,&#39;2&#39;=>3,&#39;a&#39;=>&#39;c&#39;,&#39;b&#39;=>&#39;d&#39;,&#39;c&#39;=>&#39;e&#39;];
$c = array_merge($a,$b);

var_dump($a);
var_dump($b);
var_dump($c);
?>

2. Use the implode() function to convert the merged array to a string

implode($glue ,$arr)The function can convert a one-dimensional array into a string, and will return a string composed of array elements and the "$glue" character.

var_dump($c);
var_dump(implode($c));
var_dump(implode("",$c));
var_dump(implode(",",$c));
var_dump(implode("-",$c));
var_dump(implode("::",$c));
