file_put_content资源ID＃233

Question

$data = json_encode($data, JSON_UNESCAPED_UNICODE);

$log = base_path()."/storage/logs/trade.log";

if ( !file_exists ($log) ) {
    $data = fopen($log, "w");
}

file_put_contents($log, $data . PHP_EOL.PHP_EOL, FILE_APPEND);

I have a page use file_put_contents to record log. when my folder don't exist file, it will auto create the file and add log into it

My problem is when first time auto create file and place content into it. It comes out - Resource id #233

2nd time without crate file will be normal no any problem

anyone know how to fix this?

Answer 1

fopen() returns a resource .

file_put_contents() write your file and converts $data into a string (calls __toString() on the resource ).

The second times, the file exists. So, the program doesn't pass into the if-condition and it writes $data that contains JSON.

To solve your problem, just remove your if block.

Documentation said :

If filename does not exist, the file is created. Otherwise, the existing file is overwritten, unless the FILE_APPEND flag is set.
