Make array value variable (PHP) - php

Question

Say I want to echo an array but I want to make the value in the array I echo variable, how would I do this?
Below is kind of an explanation of what I won't to do but it isn't the correct syntax.
$number = 0;
echo myArray[$number];

Answer 1

I'm not sure what you mean. What you have isn't working because you're missing a $ in myArray:
$myArray = array('hi','hiya','hello','gday');
$index = 2;
echo $myArray[$index]; // prints hello
$index = 0;
echo $myArray[$index]; // prints hi
Unlike other languages, all PHP variable types are preceded by a dollar sign.

Answer 2

Just to add more. Another type of array is associative array, where the element is determined using some identifier, usually string.
$arrayStates = array('NY' => 'New York', 'CA' => 'California');
To display the values, you can use:
echo $arrayStates['NY']; //prints New York
or, you can also use its numeric index
echo $arrayStates[1]; //prints California
To iterate all values of an array, use foreach or for.
foreach($arrayStates as $state) {
echo $state;
}
Remember, if foreach is used on non-array, it will produce warning. So you may want to do:
if(is_array($arrayStates)) {
foreach($arrayStates as $state) {
echo $state;
}
}
Hope that helps!

You are nearly there:
$number = 0;
$myArray = array('a', 'b')
echo $myArray[$number]; // outputs 'a'

Answer 4

$myArray = array("one","two","three","four");
$arrSize=sizeof($myArray);
for ($number = 0; $number < $arrSize; $number++) {
echo "$myArray[$number] ";
}
// Output: one two three four

Answer 5

$myArray = array('hi','hiya','hello','gday');
for($count=0;$count<count($myArray);$count++)
{
$SingleValue = $myArray[$count];
$AllTogether = $AllTogether.",".$SingleValue;
}
