Be VERY careful if you use range() to generate an array of numeric strings. Even though the input is quoted, the resulting array contains integers, not strings. <?php // RAY_temp_range.php error_reporting(E_ALL); // A RANGE OF NUMBERS $numbrs = range("0", "9"); // AN ARRAY OF NUMERIC CHARACTERS $alphas = array(); foreach ($numbrs as $n) { $alphas[] = "$n"; } // THEY LOOK THE SAME print_r($numbrs); echo "<br/>"; print_r($alphas); // BUT THEY ARE DIFFERENT echo "<pre>"; var_dump($numbrs); var_dump($alphas); ---- Server IP: 69.147.83.197 Probable Submitter: 98.169.58.122 ---- Manual Page -- http://www.php.net/manual/en/function.range.php Edit -- https://master.php.net/note/edit/105179 Del: integrated -- https://master.php.net/note/delete/105179/integrated Del: useless -- https://master.php.net/note/delete/105179/useless Del: bad code -- https://master.php.net/note/delete/105179/bad+code Del: spam -- https://master.php.net/note/delete/105179/spam Del: non-english -- https://master.php.net/note/delete/105179/non-english Del: in docs -- https://master.php.net/note/delete/105179/in+docs Del: other reasons-- https://master.php.net/note/delete/105179 Reject -- https://master.php.net/note/reject/105179 Search -- https://master.php.net/manage/user-notes.php
