PHP: How Do I Read From a Text File?

To read from a text file in PHP, you can use the file_get_contents function. This function reads the entire contents of a file into a string.

Here is an example of how to use file_get_contents to read from a file:

$filename = 'myfile.txt';
$contents = file_get_contents($filename);

echo $contents;

This will read the contents of the myfile.txt file and store it in the $contents variable. The contents of the file can then be displayed or processed as needed.

It's important to note that the file_get_contents function requires that the allow_url_fopen setting in your PHP configuration be enabled. This setting allows PHP to read files from local and remote locations.

You can also use the fopen, fread, and fclose functions to read from a file. These functions provide a more flexible and low-level interface for reading from files. Here is an example of how to use these functions to read from a file:

$filename = 'myfile.txt';

$file = fopen($filename, 'r');
$contents = fread($file, filesize($filename));
fclose($file);

echo $contents;

This will open the myfile.txt file for reading, read the entire contents of the file into the $contents variable, and then close the file.

It's important to note that both file_get_contents and the fopen, fread, and fclose functions can be used to read from text files and other types of files, such as binary files. However, the methods for processing the contents of the file may vary depending on the type of file being read. Consult the PHP documentation for more information.
