Hey all....
Total PHP newbie here. I posted a day ago about php working
'intermittently'. I was told to check my apache logs which was a good hint
cause php is seg faulting. I've broken it down to my connection script to my
database and I ran it in gdb to see if it would tell me anything. Since I am
linux-tarded I don't have any clue what the problem is.
Here is my php code!!! It is stored in a file called dbConnect.php
<?PHP
//DEFINE GLOBAL VARIABLES TO BE USED BY ALL DATABASE FUNCTIONS
global $g_dbConn;
function dbConnect($HostName, $UserName, $Password)
{
global $g_dbConn;
if($HostName & $UserName & $Password)
{
print($HostName);
print($UserName);
print($Password);
$g_dbConn = mysql_connect($HostName, $UserName, $Password);
if($g_dbConn)
{
print("\n" . $g_dbConn);
mysql_select_db("dba",$g_dbConn);
print("\npast select\n");
}
}
}
function dbIsConnected()
{
if($GLOBALS["g_dbConn"])
{
return true;
}
else
{
return false;
}
}
print("start\n");
dbConnect("localhost", "root", "CantSeeThis");
print("finish\n");
?>
Here is the output in GDB!!!

WTF is the problem. I have a feeling my script sucks and I am doing
something totally stupid
