==Reading a File into an Array==



<source lang="html4strict">

file() function reads the entire contents of a file into an indexed array.
Its syntax is: array file (string file [, int use_include_path])
If use_include_path is set to 1, then the file is searched along the include path in the php.ini file.
<?
$file_array = file( "data.txt" );
while ( list( $line_num, $line ) = each( $file_array ) ) :
print "<b>Line $line_num:</b> " . htmlspecialchars( $line ) . "<br>\n";
endwhile;
?>
