note 129520 added to function.preg-replace-callback-array

Note that the first replacement is applied to the whole string before the next replacement is applied. For example: <?php $subject = 'a b a b a b'; preg_replace_callback_array( [ '/a/' => function ($match) { echo '"a" found', PHP_EOL; }, '/b/' => function ($match) { echo '"b" found', PHP_EOL; } ], $subject ); ?> will print "a" found "a" found "a" found "b" found "b" found "b" found This means that you cannot use global variables to communicate information between the functions about what point in the string you have reached. ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.137 (proxied: 176.20.63.107) ---- Manual Page -- https://php.net/manual/en/function.preg-replace-callback-array.php Edit -- https://main.php.net/note/edit/129520 Del: integrated -- https://main.php.net/note/delete/129520/integrated Del: useless -- https://main.php.net/note/delete/129520/useless Del: bad code -- https://main.php.net/note/delete/129520/bad+code Del: spam -- https://main.php.net/note/delete/129520/spam Del: non-english -- https://main.php.net/note/delete/129520/non-english Del: in docs -- https://main.php.net/note/delete/129520/in+docs Del: other reasons-- https://main.php.net/note/delete/129520 Reject -- https://main.php.net/note/reject/129520 Search -- https://main.php.net/manage/user-notes.php
