Everybody seems to have their favorite use. I substitute this function for die(). It gives a
message
to the user and emails me a PrettyPrint of what went wrong. $info is set by me,
and it does a special check in the database object.
<?php
// var_format
function var_format($v) // pretty-print var_export
{
return (str_replace(array("\n"," ","array"),
array("<br>"," "," <i>array</i>"),
var_export($v,true))."<br>");
}
function myDie($info)
{
$mysqlerr=strpos($info,"ERROR=You have an error in your SQL syntax");
if($mysqlerr>0)$info=substr($info,0,$mysqlerr)." mySql format error";
$out="<br>MSG='$info'<br>".var_format($_REQUEST)."<br>";
$bt=debug_backtrace();
$sp=0;
$trace="";
foreach($bt as $k=>$v)
{
extract($v);
$file=substr($file,1+strrpos($file,"/"));
if($file=="db.php")continue; // the db object
$trace.=str_repeat(" ",++$sp); //spaces(++$sp);
$trace.="file=$file, line=$line, function=$function<br>";
}
$out.="<br>".backTrace();
if(substr($info,0,4)=="XXX ") // special errrors when db is inaccessible
{
$out=str_replace("<br>","\n",$out);
$out=str_replace(" "," ",$out);
mail("me@somewhere.com","Database Execution Error for user
".$REMOTE_ADDR,"$out");
exit("Database Access Error. Please try again later.");
}
mail("me@somewhere.com",'Error Monitor','Execution Error',$out);
exit("DANG! An execution error in the program has been sent to the webmaster.
If you don't get an email from him soon, please call him.");
}
?>
This produces an output like this
file=badmode.php, line=5, function=backTrace
file=login.php, line=209, function=require
file=midScreen.php, line=264, function=require
file=masterindex.php, line=161, function=require
file=production2.php, line=121, function=require
