I am a newbie to PHP and trying out some things to see they work .. I have tried lots of different attempts at this .. but no luck .. It is supposed to echo output 2 .. !!! I keep getting errors.
<?php
$a = array('x' => array('y' => 1, 'z' => 2, 'q' => 3,));
echo {$a['z']};//echo the value 2 from $a (tried this and it did not work.
?>
Since you have an array within an array, you need to do:
echo $a['x']['z'];
You are using an associative array, and your syntax is incorrect.
To get to z you need to go through x:
echo $a['x']['z'];
The curly braces syntax is only used when you want to access an array (called array dereferencing) inside a string (which is called variable interpolation):
echo "The value is: {$a['x']['z']}";
If you are not dereferencing a variable using the square brackets then you do not need the curly braces:
$value = $a['x']['z'];
echo "The value is: $value";
Also, you mention that you get errors. Learn what they mean and you will be able to help yourself. If you ask for help then it would also be a good idea to tell us about the errors you are getting.
Try this without braces
echo $a['z'];
Or no, you have two arrays
try
echo $a["x"]["z"];
Try simply:
<?php
$a = array('x' => array('y' => 1, 'z' => 2, 'q' => 3,));
echo $a['x']['z'];
?>
