Use a PHP program to directly call the text file content instance. How to use php (as the mainstream development language) to directly call text file content: first, use the file function to open a text file on the server, the returned myFile will become how to use php (as the current mainstream development language) to directly call the text file content: first, use the file function to open a text file on the server, the returned $ myFile will be the handle of the file operation, and then the content of each row in the file will be taken out and printed through the loop command.

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]. "").

Creation steps

1. use the file function to open a file
The following is a reference clip:
$ MyFile = file ("data.txt ");

2. loop through the array and print the elements of the array

Here

The following is a reference clip:
For ($ index = 0; $ index

For ($ index = 0; $ index {
Print ($ myFile [$ index]. "<br> ");
}

At the same time, the elements in the array are printed out.

3. program code

The following is a reference clip:


Call text file content


// Print each line while opening the file
$ MyFile = file ("data.txt ");
For ($ index = 0; $ index {
Print ($ myFile & 91; $ index & 93 ;."
");
}
?>

Using the file function to open a text file on the server, the returned myFile will become the file...
