将数组值转换为字符串可写入从$ _GET函数传入的文本文件

Question

No matter what I have tried nothing solve my problem a php file receiving content with defined variables like that

<?php
$user_id=$_GET["user_id"];
$platform=$_GET["platform"];
$devicemodel=$_GET["devicemodel"];
$deviceuuid=$_GET["deviceuuid"];

--------
and then

$content =$content. " ".$user_id;
$content =$content. " ".$platform;
$content =$content. " ".$devicemodel;
$content =$content. " ".$deviceuuid;


$file = "activities.log"; 
file_put_contents($file, $content);


?>

When I see the content of activities , I always see Array()Array()Array()Array()

No matter, what I tried to change the array type to string or text by using * implode ,var_export, print_r functions

I always see the Array()Array()Array()Array() written inside the created log file. When I write the echo $content; It seems realy fine.

What am I missing ? IS there anyone experienced the same problem?

Thanks in advance.

Actually I realized that only using the json_encode function solved my problem and started to turn the array json data to a string format which file_put_content works . Here you can the working complete code for me. Btw there was not any problem with concatenation using the lines $content=$content."" it sill works.

<?php 

$content ="--başlık--".json_encode($_GET["title"]);
$emails="--email--".json_encode($_GET["user_email"]);
$tarih="--tarih--".json_encode($_GET["tarih"]);
$categori= "--kategori--".json_encode($_GET["kategori"]);
$picturename="--picturename--".json_encode($_GET["picturename"]);
$username="--username--".json_encode($_GET["username"]);
$user_id="--userid--".json_encode($_GET["user_id"]);
$platform="--platform--".json_encode($_GET["platform"]);
$devicemodel="--devicemodel--".json_encode($_GET["devicemodel"]);
$deviceuuid="--deviceuuid--".json_encode($_GET["deviceuuid"]);


$content =$content." ".$tarih;
$content =$content." ".$emails;
$content =$content. " ".$user_id;
$content =$content. " ".$username;
$content =$content. " ".$categori;
$content =$content. " ".$platform;
$content =$content. " ".$devicemodel;
$content =$content. " ".$deviceuuid;
$content =$content. " ".$picturenam;
$file = "/*******/public_html/testupload/logs/logs-tarih-".date("Ymd").".log"; 

$content ="date---".date("F j, Y, g:i a")."--".$content."
";
//file_put_contents($file, $content, FILE_APPEND);

$fp=fopen($file,"a");
fputs($fp,$content);
fclose($fp);
