$php_errormsg

(PHP 4, PHP 5, PHP 7)

$php_errormsg — The previous error message

설명

$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.

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;
}
?>

Note: This variable doesn't seem to get populated if you're running Xdebug.

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);

?>

$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
