PHP Three modes of reading the contents of a file (RPM)

PHP three ways to read the contents of a file (go)

Share the three ways PHP reads the contents of a file.

PHP Read File contents:

2. First read mode *****************************
4. Header ("Content-type:text/html;charset=utf-8");
6. File path
8. $file _path="Text.txt";
10. Determine if you have this file
12. if (file_exists ($file _path)) {
14. if ($fp =fopen ($file _path,"A +")) {
16. Read file
18. $conn =fread ($fp,filesize ($file _path));
20. Replace string
22. $conn =str_replace ("\ r \ n","
    ",$conn);
24. Echo $conn."
    ";
26. }else{
28. echo "file is not open";
30. }
32. }else{
34. echo "does not have this file";
36. }
38. Fclose ($fp);
44. Second Read mode ***************************
46. Header ("Content-type:text/html;charset=utf-8");
48. File path
50. $file _path="Text.txt";
52. $conn =file_get_contents ($file _path);
54. $conn =str_replace ("\ r \ n","
    ",file_get_contents ($file _path));
56. echo $conn;
58. Fclose ($fp);
64. Third read mode, loop read *****************
66. Header ("Content-type:text/html;charset=utf-8");
68. File path
70. $file _path="Text.txt";
72. Determine if a file exists
74. if (file_exists ($file _path)) {
76. Determine if the file can be opened
78. if ($fp =fopen ($file _path,"A +")) {
80. $buffer = 1024;
82. Read the side of the file to determine whether the end
84. $str ="";
86. while (! Feof ($fp)) {
88. $str. =fread ($fp,$buffer);
90. }
92. }else{
94. echo "File cannot be opened";
96. }
98. }else{
100. echo "does not have this file";
102. }
104. Replace character
106. $str =str_replace ("\ r \ n","
     ",$str);
108. echo $str;
110. Fclose ($fp);
112. Functions to read the INI configuration file:
114. $arr =parse_ini_file ("Config.ini");
116. Returned is an array of
118. echo $arr [' Host '].
     ";
120. echo $arr [' username ']."
     ";
122. echo $arr [' Password ']."
     ";
