_php tutorial for invoking text file content instances directly from a PHP program

How to use PHP (as the current mainstream development language) directly invoke the text file content: First through the file function to open a text file on the server, the returned $myfile will become the handle of the operation, and then through the loop instruction, take out the contents of each line of the file and print out.

Programming Ideas

The first function to be used is fi1e, which is similar to ReadFile (), where the file function reads all the contents of the files and outputs them to the variable in the array, and each row is a separate array element. Open a Data.txt file using the file function, and the contents of the Data.txt file are:

First row 1

Second row 2

Third row 3

The statement to open the file is: $myFile =file ("Data.txt"), when $myfile is an array variable.

The contents of each element of the array are then printed by looping through the loop instruction in the arrays, and the function of count () is used here to

Gets the number of array elements.　The statement that prints the contents of the array is: print ($myFile [$index]. " ")。

Authoring steps

First, use the file function to open files
The following is a reference fragment:
$myFile =file ("Data.txt");

Second, loop through the array, print the elements of the array

Here, by

The following is a reference fragment:
for ($index =0; $index

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

Prints the contents of the elements in the array at the same time.

Third, the program code

The following is a reference fragment:


Invoke text file contents


Open a file and print each line
$myFile =file ("Data.txt");
for ($index =0; $index
{
Print ($myFile &91; $index &93;. "
");
}
?>
