file_get_contents

(PHP 4 >= 4.3.0, PHP 5)

file_get_contents -- Reads entire file into a string

Description

string file_get_contents ( string filename [, bool use_include_path [, resource context [, int offset [, int maxlen]]]] )

Identical to file(), except that file_get_contents() returns the file in a string, starting at the specified offset up to maxlen bytes. On failure, file_get_contents() will return FALSE.

file_get_contents() is the preferred way to read the contents of a file into a string. It will use memory mapping techniques if supported by your OS to enhance performance.

Note: If you're opening a URI with special characters, such as spaces, you need to encode the URI with urlencode().

Note: context parameter can be skipped by NULL.

ChangeLog

VersionDescription
5.0.0 Added the context support.
5.1.0 Added the offset and maxlen parameters.

Notes

Note: This function is binary-safe.

Tip: You can use a URL as a filename with this function if the fopen wrappers have been enabled. See fopen() for more details on how to specify the filename and Appendix N for a list of supported URL protocols.

Note: Context support was added with PHP 5.0.0. For a description of contexts, refer to Reference CLX, Stream Functions.

Warning

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.
