curl_exec 这句出错会怎么样

[tx183584]

function post($sUrl,$aPOSTParam)
{
	$oCurl = curl_init();
	if(stripos($sUrl,"https://")!==FALSE){
		curl_setopt($oCurl, CURLOPT_SSL_VERIFYPEER, FALSE);
		curl_setopt($oCurl, CURLOPT_SSL_VERIFYHOST, false);
	}
	$aPOST = array();
	foreach($aPOSTParam as $key=>$val){
		$aPOST[] = $key."=".urlencode($val);
	}
	curl_setopt($oCurl, CURLOPT_URL, $sUrl);
	curl_setopt($oCurl, CURLOPT_RETURNTRANSFER, 1 );
	curl_setopt($oCurl, CURLOPT_POST,true);
	curl_setopt($oCurl, CURLOPT_POSTFIELDS, join("&", $aPOST));

	$sContent = curl_exec($oCurl);
	if ($sContent === FALSE) {
    echo "cURL Error: " . curl_error($ch);
}
	$aStatus = curl_getinfo($oCurl);
	curl_close($oCurl);
	if(intval($aStatus["http_code"])==200){
		return $sContent;
	}else{
		echo $aStatus["http_code"];
		return FALSE;
	}
}

用curl发送post请求,curl_exec这句出错了,也不会打印值,前面的echo也效了,这是怎么回事
