Reads an entire file into an array.
Note:
You can use file_get_contents() to return the contents of a file as a string.
Path to the file.
A URL can be used as a filename with this function if the fopen wrappers have been enabled. See fopen() for more details on how to specify the filename. See the Supported Protocols and Wrappers for links to information about what abilities the various wrappers have, notes on their usage, and information on any predefined variables they may provide.
The optional parameter flags can be one, or more, of the following constants:
A context resource created with the stream_context_create() function.
Note: Context support was added with PHP 5.0.0. For a description of contexts, refer to Streams.
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.
Note:
Each line in the resulting array will include the line ending, unless
FILE_IGNORE_NEW_LINESis used, so you still need to use rtrim() if you do not want the line ending present.
Note: If PHP is not properly recognizing the line endings when reading files either on or created by a Macintosh computer, enabling the auto_detect_line_endings run-time configuration option may help resolve the problem.
file()
<?php
// Get a file into an array. In this example we'll go through HTTP to get
// the HTML source of a URL.
$lines = file('http://www.example.com/');
// Loop through our array, show HTML source as HTML source; and line numbers too.
foreach ($lines as $line_num => $line) {
echo "Line #<b>{$line_num}</b> : " . htmlspecialchars($line) . "<br />\n";
}
// Another example, let's get a web page into a string. See also file_get_contents().
$html = implode('', file('http://www.example.com/'));
// Using the optional flags parameter since PHP 5
$trimmed = file('somefile.txt', FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
