我正在尝试从服务器响应中打印最后一个字符串。我写下以下内容:
$fp = fsockopen("smtp.mail.ru", 25);
// There is fputs functions
echo fgets($fp);// This is print the first string
但我想打印服务器响应的最后一个字符串。有可能吗?
答案 0 :(得分:0)
您可以将字符串放入stings数组中,然后打印最后一个字符串:
<?php
$cntr = 0;
$strarray = [];
$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30);
if (!$fp)
{
echo "$errstr ($errno)<br />\n";
}
else
{
$out = "GET / HTTP/1.1\r\n";
$out .= "Host: www.example.com\r\n";
$out .= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
while (!feof($fp))
{
$strarray[$cntr] = fgets($fp);
$cntr = $cntr + 1;
}
fclose($fp);
}
//Now, print the last string in the array:
echo end($strarray);
?>
