我有一个以前可以使用的图片上传脚本.它现在坏了，我已经将问题追溯到一行:

I've got an image upload script which was previously working. It's now broken, and I've traced the problem down to one line:

$temp = tmpfile(); // $temp === false

tmpfile() 函数返回 false.我似乎无法弄清楚为什么.我在 Google 上很难涉足这个问题.

The tmpfile() function is returning false. I can't seem to figure out why. I'm having a hard time wading through Google on this one.

该脚本仅在运行 MAMP 1.9.5 的本地测试环境 OSX 10.6.7 上损坏.幸运的是，实时站点运行良好.

The script it only broken on my local test environment, OSX 10.6.7, running MAMP 1.9.5. Fortunately the live site is working fine.

推荐答案

tmpfile() 返回 false 如果无法创建临时文件.确保您的 tmp 文件夹可写并尝试检查 sys_get_temp_dir() 函数返回的内容.

tmpfile() returns false if it is unable to create the temporary file. Make sure your tmp folder is writable and try and check what sys_get_temp_dir() function returns.
