PHP多线程方案

1，pthreads扩展方案，结果耗损内存巨大不理想，最好少用
2，php自带curl:(满足场景要求，稳定)
function Mcurl($urls){
$pthreed = curl_multi_init(); foreach ($urls as $key => $urlInfo) {
$conn[$key]=curl_init( $urlInfo['url']); curl_setopt($conn[ $key], CURLOPT_HTTPHEADER, array("Content-type: application/json; charset=utf-8",'Accept-Encoding: gzip')); curl_setopt($conn[ $key], CURLOPT_USERAGENT, "eleme-openapi-php-sdk"); curl_setopt($conn[ $key], CURLOPT_ENCODING, "gzip"); curl_setopt($conn[ $key], CURLOPT_CUSTOMREQUEST, 'POST'); curl_setopt($conn[ $key], CURLOPT_POSTFIELDS,json_encode($urlInfo[‘data’]));
curl_setopt( $conn[$key], CURLOPT_RETURNTRANSFER,1);
curl_setopt( $conn[$key], CURLOPT_TIMEOUT,5);
curl_setopt( $conn[$key], CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt( $conn[$key], CURLOPT_SSL_VERIFYHOST, 0);
curl_multi_add_handle ( $pthreed,$conn[KaTeX parse error: Expected 'EOF', got '}' at position 11: key]); }̲ do {mrc = curl_multi_exec( $pthreed,$active);} while ( $mrc == CURLM_CALL_MULTI_PERFORM); while ($active and KaTeX parse error: Expected '}', got 'EOF' at end of input: …l_multi_select(pthreed) != -1) {
do { $mrc = curl_multi_exec($pthreed, KaTeX parse error: Expected 'EOF', got '}' at position 9: active);}̲ while (mrc == CURLM_CALL_MULTI_PERFORM);
}
}
foreach ($urls as $key => $url) {
$res[$key]=curl_multi_getcontent( $conn[$key]);
curl_close( $conn[$key]);
}
return $res;
}
