是否可以使用File_put_contents（$ fileName，$ array）以便数组中的每个项目都放在一个新行上？

Question

I am trying to rewrite a file with the contexts of an array but I want each item in the array to be on separate line. Is this possible to do?

I currently have the following:

file_put_contents('file.txt',$tempArray); 

The array has the following contents:

$tempArray = ["xyz","zyx", "123"]

and I want the file to look like this in the end:

xyz
zyx
123

but I am getting it all on one line currently

Do file_put_contents('file.txt',implode(PHP_EOL,$tempArray)); and you are fine.

• implode takes a seperator and array-values then concates them like: implode('+',array(1,2)) becomes 1+2

• PHP_EOL is an predefined constant from php that defines " " on linux and " " on windows
