我有问题。我需要从URL下载图像，但图像URL不能以JPG，PNG或其他一些img文件类型结尾。该图像由PHP脚本生成。
我如何使用PHP脚本下载此图像？

如果您在php.ini中拥有void Int_To_Text(int num) {
int first = num/10;
int second = num % 10;
if (num >= 11 && num <=20) {
switch (num) {
case 11:
cout << "Eleven";
break;
case 12:
cout << "Twelve";
break;
case 13:
cout << "Thirteen";
break;
case 14:
cout << "Fourteen";
break;
case 15:
cout << "Fifteen";
break;
case 16:
cout << "Sixteen";
break;
case 17:
cout << "Seventeen";
break;
case 18:
cout << "Eighteen";
break;
case 19:
cout << "Nineteen";
break;
case 20:
cout << "Twenty";
break;
}
}
else {
switch (first) {
case 1:
if (second == 0)
cout << "Ten";
case 2:
cout << "Twenty";
break;
case 3:
cout << "Thirty";
break;
case 4:
cout << "Fourty";
break;
case 5:
cout << "Fifty";
break;
case 6:
cout << "Sixty";
break;
case 7:
cout << "Seventy";
break;
case 8:
cout << "Eighty";
break;
case 9:
cout << "Ninety";
break;
case 10:
cout << "One Hundred";
break;
}
if(first > 1 && num != 100)
cout << " ";
switch (second) {
case 1:
cout << "One";
break;
case 2:
cout << "Two";
break;
case 3:
cout << "Three";
break;
case 4:
cout << "Four";
break;
case 5:
cout << "Five";
break;
case 6:
cout << "Six";
break;
case 7:
cout << "Seven";
break;
case 8:
cout << "Eight";
break;
case 9:
cout << "Nine";
break;
default:
break;
}
}
return;
}
int main() {
int num;
int c = 1;
cout << "Please enter a number you would like to convert" << endl;
cin >> num;
if(num > 100)
cout << "Please enter a number between 1 and 99";
else {
for(int i = 1; i <=num; i++) {
Int_To_Text(c);
c++;
cout << endl;
}
}
return 0;
}
，则可以使用file_get_contents
allow_url_fopen=1，否则，如果您安装了php-curl，则可以使用curl
$image_binary=file_get_contents($url);
。如果您既没有allow_url_fopen也没有curl，则可以使用socket api
$ch=curl_init($url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
$image_binary=curl_exec($ch);
