You can use implode you just need to use str_split first which converts the string to an array:
您可以使用内爆，您只需要首先使用 str_split 将字符串转换为数组：
$password="1bsdf4";
$formatted = implode(' ',str_split($password));

You can use chunk_splitfor this purpose.
您可以chunk_split为此目的使用。
$formatted = trim( chunk_split($password, 1, ' ') );
trimis necessary here to remove the whitespace after the last character.
trim这里有必要删除最后一个字符后的空格。

You can use this code [DEMO]:
您可以使用此代码[DEMO]：
<?php
$password="1bsdf4";
echo chunk_split($password, 1, ' ');
chunk_split()is build-in PHP function for splitting string into smaller chunks.
chunk_split()是内置的 PHP 函数，用于将字符串拆分为更小的块。

This also Worked..
这也有效..
$password="1bsdf4";
echo $newtext = wordwrap($password, 1, "\n", true);
Output: "1 b s d f 4"
输出：“1 bsdf 4”

function break_string($string, $group = 1, $delimeter = ' ', $reverse = true){
$string_length = strlen($string);
$new_string = [];
while($string_length > 0){
if($reverse) {
array_unshift($new_string, substr($string, $group*(-1)));
}else{
array_unshift($new_string, substr($string, $group));
}
$string = substr($string, 0, ($string_length - $group));
$string_length = $string_length - $group;
}
$result = '';
foreach($new_string as $substr){
$result.= $substr.$delimeter;
}
return trim($result, " ");
}
$password="1bsdf4";
$result1 = break_string($password);
echo $result1;
Output: 1 b s d f 4;
$result2 = break_string($password, 2);
echo $result2;
Output: 1b sd f4.
