CURLOPT_INTERFACE无法在php中使用

Question

I am not able to bind to my ip addresses that are set in my network interface

The following command works curl --interface 41.141.41.23 https://www.google.com

but $toSet[CURLOPT_INTERFACE] = "41.141.41.23 "; in php doesn't work and throw bind failed with errno 22: Invalid argument

I am sure that $toSet[CURLOPT_INTERFACE] = "41.141.41.23 "; is the correct way to use multiple address in my application as i have confirm with the coder and many people are using it the same way as well without any issue

My curl version is : curl 7.19.7

Answer 1

“ 41.141.41.23” =>“ 41.141.41.23”
