Help a good guy customized a crawler, it works good on my server, but after send the source code to him, he said the script can not work at all, it is strange, I asked access of his server and did a test, it really can not work!
I checked his error logs, in httpd logs, I found “call to undegined function mysql_pconnect”…, hmmmm…, he did not install php-mysql at all,
yum install php-mysql,
service httpd restart, all things works great. 🙂
So if you get the error of “mysql_pconnect”, you don’t hurry to test/debug your codes, try to check logs and it will guide to find the error, by the way, my friend is really a good guy, never do evil things, I respect him. 🙂
