5. //Determine whether this file exists
6. if(file_exists($file_path)){
7. if($fp=fopen($file_path,"a ")){
8. //Read file
9. $conn=fread($fp,filesize($file_path)); > //Replace string
$conn=
10. str_replace("rn","
    ",
$conn); 
11. echo $conn."
    ";
12. }else{ 
echo
13. "File cannot be opened";

"content-type:text/html;charset=utf-8");
//File path
$file_path=
24. "text.txt";
25. $conn=file_get_contents($file_path);
26. $conn=str_replace("rn","
    ",
file_get_contents(
27. $file_path)); 🎜> echo $conn; fclose(
$fp);
29. //******************The third reading method, loop reading****************** ***

32. //File path
33. $file_path="text.txt";
//Determine whether the file exists
35. if(file_exists(
$file_path)){
37. //Determine whether the file can be opened if($fp=
fopen(
38. $file_path,"a ")){
39. $buffer=1024; //Judge whether you have reached the end of the file while reading
40. $str="";
while(!
42. feof($fp)){ 
43. $str.=fread($fp,$buffer); }
}else{ 
44. echo "File cannot be opened";
45. }
46. }else{ 
47. echo "No such file";
48. }
49. //Replacement characters
