Php error handling
Tuesday, May 27th, 2008Sometimes we need to set our own errors rather than the default one like this.
Warning: fopen(test.txt) [function.fopen]: failed to open stream: No such file or directory in http://localhost/index.php on line 2
it is good when you create scripts and sell
Creating a basic error handler using the die function !!
if(!file_exists(“text.txt”))
{
die(“File does not exist”);
}
else
{
$file=fopen(“text.txt”,”r”);
}
?>
Set error handler
Error handlers are set using
set_error_handler(“MyErrors”);
Syntax:
<?php
function myerror($var1, $var2)
{
echo “<b>Error:</b> [$var1] $var2”;
}
set_error_handler(“myerror”);
echo($var);
?>
Error will be
Error: [8] Undefined variable: var
Thanks
