note 74886 added to language.functions

Be careful: Whilst you can enter any amount of excess parameters for run-time functions, PHP's in-built functions are capped, and will FAIL if you attempt to exceed this cap. For example: <?php implode(",",$arr); // (for reference) implode(",",$arr,$set_var); // WARNING: Wrong parameter count implode(",",$arr,$unset_var); // WARNING: Wrong parameter count implode(",",$arr,NULL); // WARNING: Wrong parameter count myimplode(",",$arr,$set_var); // Not an issue ?> The function calls that cause a 'Wrong parameter count' warning return NULL. I noticed this when trying to use $callback(...) with the values $callback = "imagecopyresampled"; and $callback = "imagecopy"; which seemed like a good idea at the time - the two functions have almost identical parameter lists, but imagecopy() would fail because it has two parameters less. ---- Server IP: 217.13.201.10 Probable Submitter: 84.46.119.224 ---- Manual Page -- http://www.php.net/manual/en/language.functions.php Edit -- https://master.php.net/note/edit/74886 Del: integrated -- https://master.php.net/note/delete/74886/integrated Del: useless -- https://master.php.net/note/delete/74886/useless Del: bad code -- https://master.php.net/note/delete/74886/bad+code Del: spam -- https://master.php.net/note/delete/74886/spam Del: non-english -- https://master.php.net/note/delete/74886/non-english Del: in docs -- https://master.php.net/note/delete/74886/in+docs Del: other reasons-- https://master.php.net/note/delete/74886 Reject -- https://master.php.net/note/reject/74886 Search -- https://master.php.net/manage/user-notes.php
