Php curl allows you to remotely download files to a local device.

Php curl allows you to remotely download an object to a local device. The result returned by this function includes the download duration, saved file name, and download method. The writing is rough. If you have good suggestions and improvement plans, please leave a message to me!

The Code is as follows:

<? Php // $ result = httpcopy ('HTTP: // www.phpernote.com/image/logo.gif'); echo '<pre>'; print_r ($ result); function httpcopy ($ url, $ file = '', $ timeout = 60) {$ file = empty ($ file )? Pathinfo ($ url, PATHINFO_BASENAME): $ file; $ dir = pathinfo ($ file, PATHINFO_DIRNAME );! Is_dir ($ dir) & @ mkdir ($ dir, 0755, true); $ url = str_replace (''," % 20 ", $ url ); $ result = array ('filename' => '', 'way' =>'', 'SIZE' => 0, 'endtime' => 0 ); $ startTime = explode ('', microtime (); $ startTime = (float) $ startTime [0] + (float) $ startTime [1]; if (function_exists ('curl _ init ') {$ ch = curl_init (); curl_setopt ($ ch, CURLOPT_URL, $ url); curl_setopt ($ ch, CURLOPT_TIMEOUT, $ timeout); curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, TRUE ); $ Temp = curl_exec ($ ch); if (@ file_put_contents ($ file, $ temp )&&! Curl_error ($ ch) {$ result ['filename'] = $ file; $ result ['way'] = 'curl '; $ result ['SIZE'] = sprintf ('%. 3f', strlen ($ temp)/1024) ;}} else {$ opts = array ('http' => array ('method' => 'get ', 'header' => '', 'timeout' => $ timeout); $ context = stream_context_create ($ opts); if (@ copy ($ url, $ file, $ context) {$ result ['filename'] = $ file; $ result ['way'] = 'copy '; $ result ['SIZE'] = sprintf ('%. 3f', strlen ($ context)/1024) ;}$ endTime = explode ('', microtime (); $ endTime = (float) $ endTime [0] + (float) $ endTime [1]; $ result ['endtime'] = round ($ endTime-$ startTime) * 1000; // unit: millisecond return $ result ;}
