Use fopen(), fread(), and fclose() to open, read, and close a file

                
                    <?php
                    $myfile = fopen("webdictionary.txt", "r") or die("Unable to open file!");
                    echo fread($myfile,filesize("webdictionary.txt"));
                    fclose($myfile);
                    ?>
                
                

Use fgets() to read a single line from a file

                
                    <?php
                    $myfile = fopen("webdictionary.txt", "r") or die("Unable to open file!");
                    echo fgets($myfile);
                    fclose($myfile);
                    ?>
                
                

Use feof() to read through a file, line by line, until end-of-file is reached

                
                    <?php
                    $myfile = fopen("webdictionary.txt", "r") or die("Unable to open file!");
                    // Output one line until end-of-file
                    while(!feof($myfile)) {
                      echo fgets($myfile) . "<br>";
                    }
                    fclose($myfile);
                    ?>
                
                

Use fgetc() to read a single character from a file

                
                    <?php
                    $myfile = fopen("webdictionary.txt", "r") or die("Unable to open file!");
                    // Output one character until end-of-file
                    while(!feof($myfile)) {
                      echo fgetc($myfile);
                    }
                    fclose($myfile);
                    ?>
