Please submit a single PHP source file that isready for execution. To get full credit you also need to make sure that you check for error returns from any of the APIs that you do use. If there is an error simply echo an message indicating that an error occurred.
1. You need to open a fileorders.txtfor writing. Modify the following code, specifically the twoplaceholders, to accomplish your goal.
$fp =___("$document_root/../orders/orders.txt", '___');
2. Use the PHPfwritefunction to write a string stored in$outputstring(you choose the content of the string)to the file pointed to by$fp.
For example,
$outputstring = "This is a sample string. You can use this as is or create your own string to be written to a file";
3. Use a PHP File IO function to close the file. Then reopen the file for reading.
4. You need to use a PHP while loop to read from a file until the end of the file is reached. Modify the following code to accomplish your goal. As before, you will need to find the correct File IO API to accomplish this
while (!___($fp))
5. Use PHP toechothe size (in bytes) of the fileorders.txt.
