Function description
String file_get_contents (string $ filename [, bool $ use_include_path [, resource $ context [, int $ offset [, int $ maxlen])
Like file (), only file_get_contents () can read the file into a string. The content with the length of maxlen will be read at the position specified by the offset parameter. If it fails, file_get_contents () returns FALSE.

The file_get_contents () function is used to read the file content into a string. If the operating system supports it, the memory ing technology will be used to enhance the performance.

Application:

The code is as follows: Copy code

$ Str = $ content = file_get_contents ("2. SQL", FALSE, NULL, 1024 );
Echo $ str;

If you only want to read small files in segments and read them in this way, you can use the fread () function.

The code is as follows: Copy code

$ Fp = fopen ('2. SQL ', 'r ');
While (! Feof ($ fp )){
$ Str. = fread ($ fp, filesize ($ filename)/10); // read 1 out of 10 at a time
// Process
}

Echo $ str;
