Fread () reads data from an external file and reports it back to your PHP file. It read the number of bytes that you specify. fread() reads up to length bytes from the file pointer referenced by handle It is phrased as: fread ( handle, length ). You must open the file in the handle. The length is measured in bytes, with a 8192 byte maximum.

Use the 'r' option to open a file as read-only. When a file is opened as read-only, the file pointer is placed in the beginning of the file and you start reading from there. The PHP function fgets () is used to read a file line by line. This will only work if the file data is stored on separate new lines, if it is not this will not produce the results you are looking for. w+ is use to Read/Write. Opens and clears the contents of file; or creates a new file if it doesn't exist.

Read/Write: 'r+' > Opens a file so that it can be read from and written to. The file pointer is at the beginning of the file. Append: 'a+' > This is exactly the same as r+, except that the pointer which is appear in file is at the end of the file. The difference with 'r+' is that the file pointer is positioned at the end of the file. Write/Read: 'w+' > This is exactly the same as r+, except that it deletes all information in the file when the file is opened.
