note 78395 added to function.preg-replace

I found something strange <?php $string = 'The quick brown fox jumped over the lazy dog.'; $patterns[0] = '/quick/'; $patterns[1] = '/brown/'; $patterns[2] = '/fox/'; $replacements[2] = 'bear'; $replacements[1] = 'black'; $replacements[0] = 'slow'; echo preg_replace($patterns, $replacements, $string); ?> Output The bear black slow jumped over the lazy dog. But when you swap the replacements like $replacements[0] = 'slow'; $replacements[2] = 'bear'; $replacements[1] = 'black'; you get The slow bear black jumped over the lazy dog. ---- Server IP: 83.137.20.107 Probable Submitter: 213.84.213.133 ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace.php Edit -- https://master.php.net/note/edit/78395 Del: integrated -- https://master.php.net/note/delete/78395/integrated Del: useless -- https://master.php.net/note/delete/78395/useless Del: bad code -- https://master.php.net/note/delete/78395/bad+code Del: spam -- https://master.php.net/note/delete/78395/spam Del: non-english -- https://master.php.net/note/delete/78395/non-english Del: in docs -- https://master.php.net/note/delete/78395/in+docs Del: other reasons-- https://master.php.net/note/delete/78395 Reject -- https://master.php.net/note/reject/78395 Search -- https://master.php.net/manage/user-notes.php
