$php_errormsg

(PHP 4, PHP 5)

$php_errormsgThe previous error message

Description

$php_errormsg is a variable containing the text of the last error message generated by PHP. This variable will only be available within the scope in which the error occurred, and only if the track_errors configuration option is turned on (it defaults to off).

Warning

If a user defined error handler (set_error_handler()) is set $php_errormsg is only set if the error handler returns FALSE.

Examples

Example #1 $php_errormsg example

<?php
@strpos();
echo 
$php_errormsg;
?>

The above example will output something similar to:

The track_errors parameter is PHP_INI_ALL, so you can use code like this:

<?php
ini_set
('track_errors'1);

$result = @do_risky_thing();
if (! 
$result) {
    echo 
'<p>Error' htmlspecialchars($php_errormsg) . '</p>';
}

ini_set('track_errors'0);
?>

While $php_errormsg is a global, it is not a superglobal.

You'll have to qualify it with a global keyword inside a function.

<?php
function checkErrormsg()
{
    global 
$php_errormsg;
    @
strpos();
    return 
$php_errormsg;
}
?>

$php_errormsg does not contain the error message generated inside a function. See the example below:
<?php
@strpos();
function 
checkErrormsg()
{
    global 
$php_errormsg;
    echo 
"First Error is: $php_errormsg <br />";
    @
ini_set();
    echo 
"Error is: $php_errormsg";
}
checkErrormsg();
?>
This will output:
First Error is: strpos() expects at least 2 parameters, 0 given 
Error is: strpos() expects at least 2 parameters, 0 given
