file_put_contents包含多个变量

Question

I'm trying to figure out how to write multiple variables to file using file_put_content.

My code:

<?php
$file = 'file.txt';
$data1 = "John Smith";
file_put_contents($file, $data1, FILE_APPEND | LOCK_EX);
?>

I have additional variables such as $data2, $data3 and $data4. I tried:

<?php
$file = 'file.txt';
$data1 = "John Smith";
$data2 = "Street Address";
$data3 = "Plumber";
$data3 = "Phone nuber";
file_put_contents($file, $data1, $data2, $data3, $data4,FILE_APPEND | LOCK_EX);
?>

but it's not working. I need to write all variables to file.txt so it looks like this:

John Smith Stret Address Plumber Phone Number

and each time when the script has been launched it should add new variables in a new line e.g:

John Smith Stret Address Plumber Phone Number
Mike Johnson Stret Address lectrician Phone Number

etc etc. Any ideas? :)

Answer 1

I would do it this way:

<?php
$file = 'file.txt';

$data1 = "John Smith";
$data2 = "Street Address";
$data3 = "Plumber";
$data3 = "Phone nuber";

$data = array($data1, $data2, $data3, $data4);

file_put_contents($file, implode(' ',$data)."
",FILE_APPEND | LOCK_EX);
?>

You can create array and implode it using any separator you want and concatenate implode result with new line .
