## Three PHP questions

PHP Code:
``` <?php     // Open the text file     \$f = fopen("textfile.txt", "w");     // Write text     fwrite(\$f, \$_POST["name"]);      //space     fwrite(\$f, \$_POST["email"]);     // Close the text file     fclose(\$f);     // Open file for reading, and read the line     \$f = fopen("textfile.txt", "r");     // Read text     echo fgets(\$f);      fclose(\$f);     ?> ```
Hi I have two problems:

1) How can you close the php file and open another separate URL link after ?

2) Have it so that that it doesn't replace the previous text on the text file it just writes another bellow?

3) How do I get a space between the two "Write text's" look for:
PHP Code:
``` //space  ```
?
