fileputcontens中的文件大小

Question

When I use file_put_contents and want put long string with 5Mb info to file, it create me 1Mb file, cut a first 1M of string. Why? What I need to do to write all 5 Mb to file?

Answer 1

1) What about your post_max_size value in your php.ini? It should be greater than 1M.

2) If you are storing data in a for(each) loop, you should use file_put_contents($in_file, $data, FILE_APPEND) flag, otherwise the file is overwritten in each pass of the loop and its content is only last value of stored variable.
