在一条线上执行阵列项目的功能

Question

<?php 
$fruits = "lemon 
    orange 
banana 
apple 
    pear"; 

$fruits_a = explode("\n", $fruits); 
for ($i = 0; $i < count($fruits_a); $i++) 
{ 
    $fruits_a[$i] = trim($fruits_a[$i]); 
} 
$fruits = implode(" ", $fruits_a); 

echo $fruits; 
?> 

是否可以将此（从爆炸到爆炸）转换为单行？ 在蟒蛇这纯粹是fruits = " ".join(x.strip() for x in fruits.split("\n"))

$fruits = implode(
    ' ', 
    array_map(
     'trim', 
     explode("\n", $fruits) 
    ) 
); 

Answer 2

是的，它是

$fruits = implode(' ', array_map('trim', explode('\n', $fruits)));
