What are some alternative methods in PHP for reading source code?

When working with PHP, there are various methods to read the source code of a file. One common approach is to use the file_get_contents() function in PHP, which reads the entire contents of a file into a string. Another method is to use the fopen() function to open a file and then read its contents line by line using functions like fgets() or fgetc(). Additionally, PHP provides the file() function, which reads a file into an array, with each element representing a line of the file.

// Using file_get_contents() to read the source code of a file
$sourceCode = file_get_contents('myfile.php');
echo $sourceCode;
```

```php
// Using fopen() and fgets() to read the source code of a file line by line
$handle = fopen('myfile.php', 'r');
if ($handle) {
    while (($line = fgets($handle)) !== false) {
        echo $line;
    }
    fclose($handle);
}
```

```php
// Using file() to read the source code of a file into an array
$sourceCodeArray = file('myfile.php');
foreach ($sourceCodeArray as $line) {
    echo $line;
}
