PHP 写入文本文件从字符串末尾截断文本

Question

In my code I have to write multiple json strings to files. When I do so, the end of what's being written is cut off by a seemingly random amount of characters.

I originally tried using fwrite() , then tested using just file_put_contents() , but both methods of writing to file cut off the characters. That code snippet looks like this:

print_r( json_encode($verified_results) );
file_put_contents($results_file, json_encode($verified_results));
/*$fh = fopen($results_file, 'w'); // or die("can't open file");
$stringData = json_encode($verified_results) ;
fwrite($fh, $stringData);

fclose($fh);
print_r(preg_last_error());
*/

I know that the json string is intact post-write, as the print_r returns the full string before writing it to file.

The text that's being cut off is:
108 characters

 5","elapsedTime":"11 hours ago","hotel_cat":null,"visible":true,"hash_id":"22aa8da3d0b8ef44ec07f8521986fbac"}]

110 characters

 5","elapsedTime":"11 hours ago","hotel_cat":null,"visible":true,"hash_id":"22aa8da3d0b8ef44ec07f8521986fbac"}]

The first file is 47KB in size, and the cut off point leaves 108 characters at a random point (not due to an invalid character).

The second file is 52KB in size, and the cut off point leaves 110 characters, once again, at a random point.

What could be causing this with such a small file?

(Full code)

 foreach ($sift_usernames as $key => $user) { $username = $user['username']; if(is_dir(APP_ROOT."sift_users/".$username)) { if(is_file((APP_ROOT."sift_users/". $username.

An old question but anyone else scrambling for a fix,

For me on my Dev server I changed the following in the PHP.ini file: max_input_vars = 5000 and up'd both the input time and memory limit:

max_input_time = 180 memory_limit = 512M

Pretty sure only the input vars was needed but not tested it
