Use a PHP program to directly call the content instance of a text file

How to Use php to directly call the text file content: First, open a text file on the server through the file function, the returned $ myFile will become the handle of the file operation, and then use the circular command, extract and print the content of each row in the file.

Programming Logic

The first function to be used is fi1e. This function is similar to readfile (). in different places, the file function reads all the content in the file, and output to the array variables, each row is a separate array element. Use the file function to open a data.txt file. The content of the data.txt file is:

First line 1

Row 2

Row 3

The statement for opening a file is $ myFile = file ("data.txt"). $ myFile is an array variable.

Then print the content of each element of the array through the loop command loop in the array. Here the count () function is used

Obtains the number of array elements. Print ($ myFile [$ index]. "").
