dinita Posted October 10, 2012 Share Posted October 10, 2012 quick question really.. trying to call an extract function where the keys of the array are numbers? a variable cannot start with a number, so how would I call my new variables?

salathe Posted October 10, 2012 Share Posted October 10, 2012 Use a prefix, see the extract() docs. However, do you really need to extract those values into variables, more often than not it makes more sense to keep working with the array.

ManiacDan Posted October 10, 2012 Share Posted October 10, 2012 Don't use extract at all, just use the array. If you use extract, you're creating mystery variables and duplicating content.

nodirtyrockstar Posted October 10, 2012 Share Posted October 10, 2012 Start them with an underscore? You can add/remove it dynamically. Or use a letter, or some other allowed character.

Christian F. Posted October 10, 2012 Share Posted October 10, 2012 ManiacDan's post is the one that you should go for, without doubt. If your code absolutely requires the use of extract (), then you're most likely doing it wrong.

salathe Posted October 10, 2012 Share Posted October 10, 2012 you're most likely doing it wrong. No need to repeat what other people have already said. Thanks.

dinita Posted October 11, 2012 Author Share Posted October 11, 2012 your right I was doing it wrong! I thought I needed the array to split into separate variables so the Actionscript could read these and display them into separate boxes by calling each variable. Instead I've used the array to echo a string split using backslashes and removed the backslashes in the Actionscript using the split function and then turned that string into an array. Thanks for being so patient with me! Link to comment https://forums.phpfreaks.com/topic/269311-extract-function/#findComment-1384544 Share on other sites More sharing options...
