I actually have three questions, all regarding to PHP & mySQL, but three different areas. This could be three seperate topics, but I figured that posting all at once would make things a little easier for everyone.
Upon reading the manual, I cannot find a difference between mysql_connect() and mysql_pconnect() other than that pconnect opens up a "persistant" connection. What does that mean? Whats the difference between opening a "regular" connection and a "persistant" connection?
When accessing a mysql database, and using information from different tables within many different functions across different files; would it be better to have one global connection and declare the resource global in each function or open/close the database as needed per function. I would think that one global variable would do it, but does that pose any drawbacks?
I dont remember if I have asked this question before or not, but im still having problems so ill ask again. My apoligies if this is a repost. I have a call to mysql_query() and the " or die(mysql_error());" clause at the end of it. Now, the script does stop, however, it does not output an error. I have outputted the sql statement, and it is valid (or at least as far as I can see). I do pass in a globally declared connection resource (which works throughout other query calls). How can I figure out the cause of the problem with no error message?
Sorry for the mix of questions, but I got kinda confused and could not find the information I was looking for inside of the manual or on the net. Thanks for any help in advance.
