Php three ways to read file content) _ PHP Tutorial

Php can read file content in three ways (convert ). Php reads the file content: ********************** * ****** header (content-type: texthtml?charset=8w.w.w.w.w.w.file_pathtext.txt; php reads the file content:

1. // ************** First method of reading ******************** *********
2. Header ("content-type: text/html; charset = utf-8 ");
3. // File path
4. $ File_path = "text.txt ";
5. // Determine whether the file exists
6. If (file_exists ($ file_path )){
7. If ($ fp = fopen ($ file_path, "a + ")){
8. // Read the file
9. $ Conn = fread ($ fp, filesize ($ file_path ));
10. // Replace the string
11. $ Conn = str_replace ("\ r \ n ","
    ", $ Conn );
12. Echo $ conn ."
    ";
13. } Else {
14. Echo "file cannot be opened ";
15. }
16. } Else {
17. Echo "this file does not exist ";
18. }
19. Fclose ($ fp );
22. // ******************* Second read method *************** ************
23. Header ("content-type: text/html; charset = utf-8 ");
24. // File path
25. $ File_path = "text.txt ";
26. $ Conn = file_get_contents ($ file_path );
27. $ Conn = str_replace ("\ r \ n ","
    ", File_get_contents ($ file_path ));
28. Echo $ conn;
29. Fclose ($ fp );
32. // ******************** The third read method, cyclically read *****************
33. Header ("content-type: text/html; charset = utf-8 ");
34. // File path
35. $ File_path = "text.txt ";
36. // Determine whether a file exists
37. If (file_exists ($ file_path )){
38. // Determine whether the file can be opened
39. If ($ fp = fopen ($ file_path, "a + ")){
40. $ Buffer = 1024;
41. // Read and judge whether the object ends
42. $ Str = "";
43. While (! Feof ($ fp )){
44. $ Str. = fread ($ fp, $ buffer );
45. }
46. } Else {
47. Echo "file cannot be opened ";
48. }
49. } Else {
50. Echo "this file does not exist ";
51. }
52. // Replace the character
53. $ Str = str_replace ("\ r \ n ","
    ", $ Str );
54. Echo $ str;
55. Fclose ($ fp );
56. Functions used to read the INI configuration file:
57. $ Arr = parse_ini_file ("config. ini ");
58. // The returned result is an array.
59. Echo $ arr ['host']."
    ";
60. Echo $ arr ['username']."
    ";
61. Echo $ arr ['password']."
    ";
