Description: ------------ When using both curl and multi_curl i get a curl_errno of 0 for each handle while an curl_error results a string error. When using multi_curl the error string is: Failed connect to ftp.nmh.ac.uk:21; Operation now in progress When using curl the error string is: couldn't connect to host Using multi_curl results in a null body returned with curl_multi_getcontent Using curl yields the data of the file when using curl_exec Test script: --------------- two scripts are below to reproduce. # multi_curl method <?php $curls = array(); $cmh = curl_multi_init(); $dlFiles = array( 'ftp://ftp.nmh.ac.uk/wdc/obsdata/hourval/single_year/1914/sod1914.wdc', 'http://spc.igpp.ucla.edu/uclamag/ffi/lal/B99300_LAL.ffd', 'ftp://ftp.nmh.ac.uk/wdc/obsdata/hourval/single_year/1922/hua1922.wdc', 'http://vmo.igpp.ucla.edu/data1/Weygand/ProcessedSolarWindGSE/ACE/mag/2000/acemag200001.dat' ); foreach ($dlFiles as $x => $file) { $curls[$x] = curl_init(); curl_setopt($curls[$x], CURLOPT_URL, $file); curl_setopt($curls[$x], CURLOPT_RETURNTRANSFER, 1); curl_setopt($curls[$x], CURLOPT_FOLLOWLOCATION, 1); curl_multi_add_handle($cmh, $curls[$x]); } $active = null; do { $mrc = curl_multi_exec($cmh, $active); } while ($mrc == CURLM_CALL_MULTI_PERFORM); while ($active && $mrc == CURLM_OK) { if (curl_multi_select($cmh) != -1) { do { $mrc = curl_multi_exec($cmh, $active); } while ($mrc == CURLM_CALL_MULTI_PERFORM); } } foreach ($dlFiles as $x => $file) { var_dump(substr(curl_multi_getcontent($curls[$x]), 0, 10), curl_errno($curls[$x]), curl_error($curls[$x])); curl_multi_remove_handle($cmh, $curls[$x]); curl_close($curls[$x]); } curl_multi_close($cmh); ?> # curl method <?php $dlFiles = array( 'ftp://ftp.nmh.ac.uk/wdc/obsdata/hourval/single_year/1914/sod1914.wdc', 'http://spc.igpp.ucla.edu/uclamag/ffi/lal/B99300_LAL.ffd', 'ftp://ftp.nmh.ac.uk/wdc/obsdata/hourval/single_year/1922/hua1922.wdc', 'http://vmo.igpp.ucla.edu/data1/Weygand/ProcessedSolarWindGSE/ACE/mag/2000/acemag200001.dat' ); foreach ($dlFiles as $x => $file) { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $file); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); var_dump(substr(curl_exec($ch), 0, 10), curl_errno($ch), curl_error($ch)); curl_close($ch); } ?> Expected result: ---------------- no errors at all and multi_curl letting me get the contents of the curl.
