this is the complete code which i have written for viewing the html source code of a form.this
works fine for blank values/valid values entered in the site name.
The problem is here :If i enter an invalid address
like
"http://www."
"http://www.abc.du" etc ,then the textarea displays this error message:
"Unable to access domain.Please verify address and try again"(which is fine).
The problem is that along with this i get the following error too.
"Warning: fopen() [function.fopen]: php_network_getaddresses: getaddrinfo failed: Name or service not known in /home2/king/engine-www/tools/html-code.php on line 247
Warning: fopen(http://www.abc.du) [function.fopen]: failed to open stream: No such file or directory in /home2/king/engine-www/tools/html-code.php on line 247"
note : Line 247 is "fopen".how do i rectify the above error.pls help.
once again how do i change fopen for invalid URL's
