阅读更多关于 How to get the content-type of a file in PHP?

I'm using PHP to send an email with an attachment. The attachment could be any of several different file types (pdf, txt, doc, swf, etc). First, the script gets the file using "file_get_contents". Later, the script echoes in the header: Content-Type: <?php echo $the_content_type; ?>; name="<?php echo $the_file_name; ?>" How to I set the correct value for $the_content_type ? I am using this function, which includes several fallbacks to compensate for older versions of PHP or simply bad results: function getFileMimeType($file) { if (function_exists('finfo_file')) { $finfo = finfo_open(FILEINFO

Get content between two strings PHP

阅读更多关于 Get content between two strings PHP

Whats is the best way to obtain the content between two strings e.g. ob_start(); include('externalfile.html'); ## see below $out = ob_get_contents(); ob_end_clean(); preg_match('/{FINDME}(.|\n*)+{\/FINDME}/',$out,$matches); $match = $matches[0]; echo $match; ## I have used .|\n* as it needs to check for new lines. Is this correct? ## externalfile.html {FINDME} Text Here {/FINDME} For some reason this appears to work on one place in my code and not another. Am I going about this in the right way? Or is there a better way? Also is output buffer the way to do this or file_get_contents? Thanks in
