Is there a way to get the last error in php4 - error-handling

Question

PHP 5 has error_get_last. Is there any way to completely or at least partially replicate the same functionality in PHP4.3?

Answer 1

Ripped from the PHP manual (courtesy of php at joert dot net):
<?php
if( !function_exists('error_get_last') ) {
set_error_handler(
create_function(
'$errno,$errstr,$errfile,$errline,$errcontext',
'
global $__error_get_last_retval__;
$__error_get_last_retval__ = array(
\'type\' => $errno,
\'message\' => $errstr,
\'file\' => $errfile,
\'line\' => $errline
);
return false;
'
)
);
function error_get_last() {
global $__error_get_last_retval__;
if( !isset($__error_get_last_retval__) ) {
return null;
}
return $__error_get_last_retval__;
}
}
?>

Yes it is, but you will have to do some programming, you need to attach error handler
$er_handler = set_error_handler("myErrorHandler");
but before this you need to write your "myErrorHandler"
function myErrorHandler($errNumber, $errString, $errFile, $errLine)
{
/*now add it to session so you can access it from anywhere, or if you have class with the static variable you can save it there */
$_SESSION["Error.LastError"] = $errNumber . '<br>' . $errString . '<br>' . $errFile . '<br>' . $errLine;
}
Now when error is occured you can get it by
if(isset($_SESSION["Error.LastError"]))
$str = $_SESSION["Error.LastError"];
now to replicate your method you need to create function
function get_last_error()
{
$str = "";
if(isset($_SESSION["Error.LastError"]))
$str = $_SESSION["Error.LastError"];
return $str;
}
