note 92752 added to function.implode

As "john" pointed out on 2004 Apr 26, implode does not always work in a way that could be considered intuitive. You may need to sort your elements with ksort, or write a longer routine to fill in any "gaps". See this example: <?php $a = array(1=>'one', 7=>'seven', 5=>'five'); $b = implode (',', $a); ksort ($a); $c = implode (',', $a); $highest = max(array_keys($a)); for ($i = 0; $i <= $highest; ++$i): if (! isset($a[$i])): $a[$i] = ''; endif; endfor; ksort ($a); $d = implode (',', $a); print "\$b = '$b'<br>\n"; print "\$c = '$c'<br>\n"; print "\$d = '$d'<br>\n"; /* output: $b = 'one,seven,five' $c = 'one,five,seven' $d = ',one,,,,five,,seven' */ ?> ---- Server IP: 208.69.120.35 Probable Submitter: 67.165.168.203 ---- Manual Page -- http://www.php.net/manual/en/function.implode.php Edit -- https://master.php.net/note/edit/92752 Del: integrated -- https://master.php.net/note/delete/92752/integrated Del: useless -- https://master.php.net/note/delete/92752/useless Del: bad code -- https://master.php.net/note/delete/92752/bad+code Del: spam -- https://master.php.net/note/delete/92752/spam Del: non-english -- https://master.php.net/note/delete/92752/non-english Del: in docs -- https://master.php.net/note/delete/92752/in+docs Del: other reasons-- https://master.php.net/note/delete/92752 Reject -- https://master.php.net/note/reject/92752 Search -- https://master.php.net/manage/user-notes.php
