function - PHP Error Handling - "missing argument for errorHandler" -


i'm trying setup error handling first time.
work , report errors if there one, reason shows errors of 'missing arguments' error handling function itself. please note error handling function in separate file , included index page, i'm not sure if that's problem :s

here error handling function

function errorhandler($errno, $errstr, $error_file, $error_line) { if(isset($errstr)) { # there error, display echo $errno." - ".$errstr." in ".$error_file." @ line ".$error_line."<br>"; } else { # there isn't error, nothing return false; } } // must tell php use above error handler. set_error_handler("errorhanlder");

here index page 

<!-- # error handler --> <? if(errorhandler()) { ?> <section id="error-handler"> <?=errorhandler();?> </section> <? } ?>

here result in browser (bear in mind there no php error, error handler shouldn't outputting - can't understand

2 - missing argument 1 errorhandler(), called in index.php on line 20 , defined in inc/arcerror.fnc.php @ line 10 2 - missing argument 2 errorhandler(), called in index.php on line 20 , defined in inc/arcerror.fnc.php @ line 10 2 - missing argument 3 errorhandler(), called in index.php on line 20 , defined in inc/arcerror.fnc.php @ line 10 2 - missing argument 4 errorhandler(), called in index.php on line 20 , defined in inc/arcerror.fnc.php @ line 10

any idea's why php reporting missing arguments?

you calling function 0 argument... 

<?=errorhandler();?>

why need call anyway?

and there several typos in code: replace "hanlder" "handler".

there's no need that:

if(isset($errstr)) {

your error-handling function automatically called when there error (and in case!). $errstr parameter of function, set when function gets executed.

new code:

function errorhandler($errno, $errstr, $error_file, $error_line) { # there error, display echo "<section id='error-handler'>$errno - $errstr in $error_file @ line $error_line</section><br>"; } // must tell php use above error handler. set_error_handler("errorhandler");

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
