Identical to file_get_contents(), except that file() returns the file in an array. Each element of the array corresponds to a line in the file, with the newline still attached. Upon failure, file() returns FALSE.
You can use the optional use_include_path parameter and set it to "1", if you want to search for the file in the include_path, too.

注: Each line in the resulting array will include the line ending, so you still need to use rtrim() if you do not want the line ending present.

注: As of PHP 4.3.0 you can use file_get_contents() to return the contents of a file as a string.
In PHP 4.3.0 file() became binary safe.
注: Context support was added with PHP 5.0.0. For a description of contexts, refer to 參考 CLIII, Stream Functions.
警告 |
When using SSL, Microsoft IIS will violate the protocol by closing the connection without sending a close_notify indicator. PHP will report this as "SSL: Fatal Protocol Error" when you reach the end of the data. To workaround this, you should lower your error_reporting level not to include warnings. PHP 4.3.7 and higher can detect buggy IIS server software when you open the stream using the https:// wrapper and will suppress the warning for you. If you are using fsockopen() to create an ssl:// socket, you are responsible for detecting and suppressing the warning yourself. |
