How to Read a File Into an Array With PHP
PHP is a high-level scripting language often used on Web servers, although you can also use it as a command line language. You can use PHP to open a text file and read the contents of that file into an array. The PHP \"explode\" function is the function that will actually place the contents of the file into the array. The \"explode\" function returns an array of strings separated by a delimiter. The file is processed line by line using the \"fgets\" function.
