Below we will explain it to you one by one through specific code examples.

Code sample method 1:

<?php
$arr=[&#39;PHP&#39;,&#39;Python&#39;,&#39;Java&#39;,&#39;C&#39;];
$str=implode(glue:&#39; &#39;,$arr);
 var_dump($arr);
 var_dump($str);

In the above code, first we create an $arr array, which is assigned four different values; then we use the implode function to $arr Arrays are converted to strings. Everyone should understand that there are two parameters in the PHP implode() function. The first parameter glue:’ ’ represents a splicing character that connects the elements in the array, and the second parameter is the array we need to convert; here we use the $str variable to receive the value of the array converted to a string. Finally, use var_dump to print out the two variable values ​​separately.

Then we access it through the browser, and the printed result is as shown below:

You can find that the $arr array has been converted into a string.

Code sample method 2:

<?php
$arr=[&#39;PHP&#39;,&#39;Python&#39;,&#39;Java&#39;,&#39;C&#39;];
$str=&#39; &#39;;
foreach ($arr as $v){
   $str1 .=&#39; &#39;.$v;
}
var_dump($str1);

In this code, we first define a $str1 variable and assign it to empty, and then use a foreach loop to change each value in the $arr array Assign values ​​to $v respectively, and then use dots to connect the strings. Finally, use var_dump to print out $str1 to see if the return value of $str1 is a string.

We continue to access through the browser, and the displayed result is as follows:

You should also be able to see that the array can be converted into characters through loop traversal. String display.
