note 112069 added to function.array-flip

This function is useful when parsing a CSV file with a heading column, but the columns might vary in order or presence: <?php $f = fopen("file.csv", "r"); /* Take the first line (the header) into an array, then flip it so that the keys are the column name, and values are the column index. */ $cols = array_flip(fgetcsv($f)); while ($line = fgetcsv($f)) { // Now we can reference CSV columns like so: $status = $line[$cols['OrderStatus']]; } ?> I find this better than referencing the numerical array index. ---- Server IP: 69.147.83.199 Probable Submitter: 217.34.54.3 ---- Manual Page -- http://php.net/manual/en/function.array-flip.php Edit -- https://master.php.net/note/edit/112069 Del: integrated -- https://master.php.net/note/delete/112069/integrated Del: useless -- https://master.php.net/note/delete/112069/useless Del: bad code -- https://master.php.net/note/delete/112069/bad+code Del: spam -- https://master.php.net/note/delete/112069/spam Del: non-english -- https://master.php.net/note/delete/112069/non-english Del: in docs -- https://master.php.net/note/delete/112069/in+docs Del: other reasons-- https://master.php.net/note/delete/112069 Reject -- https://master.php.net/note/reject/112069 Search -- https://master.php.net/manage/user-notes.php
