php version of myVariable.getArray()[0].myVariable

Hey Guys,

Is a php version of this javascript code?

myVariable.getArray()[0].myVariable

Code (markup):

I want to be able to get the first variable in the array but without having to create a new variable to hold the array.

 

Um, well that depends..? Can you show us your PHP code / where you're getting the array from? Because a variable is either an array or it's not so you wouldn't have to create a new variable to hold it. Unless, of course, you're calling a function that returns an array (whether it's a function you created or a built-in one like explode()) in which case you can try to do callToFunction()[0] which would return the first value in the array.

I'm not 100% if that'll work, I've honestly never tried to touch an array directly like that, so it might not work. But either way, in PHP, to access the first value of an array, just do $array_name[0]

 

Hi,

Be more specific about what you need!

In PHP if you an array say with the name $myVariable, then to access the first element in you can simply write $myVariable[0].

I'm trying to get data from a xml file.

This is the xml file.

<?xml version="1.0" encoding="utf-8"?>
<settings>
  <sitename>AutoVideoScript 6.5</sitename>
  <sitetitle>Run your own Youtube clone web site</sitetitle>
  <sitedescription>This site is powered by AutoVideoScript 6.</sitedescription>
  <sitekeywords>youtube sharing script, media script</sitekeywords>

</settings>

Code (markup):

This is the javascript that works.

        var mysettings = xmldata.getElementsByTagName("settings")[0];
        
        var sitename = mysettings.getElementsByTagName("sitename")[0].firstChild.data;
       	var sitetitle = mysettings.getElementsByTagName("sitetitle")[0].firstChild.data;
        var sitedescription = mysettings getElementsByTagName("sitedescription")[0].firstChild.data;

Code (markup):

I want to do the same way in php but its not a correct syntax because of [0].

mysettings->getElementsByTagName("sitiename")[0]->firstChild->data

Code (markup):

 

I figured it out.

mysettings->getElementsByTagName("sitiename")->item[0]->firstChild->data

Code (markup):
