How to access a certain array inside an array: PHP

Question

I know this is pretty stupid but i'm wondering how to access the FIFTH array inside this array.

 array(1) {
 [0] = > string(3)"913"
 }
 array(2) {
 [0] = > string(3)"913"
 [1] = > string(2)"95"
 }
 array(3) {
 [0] = > string(3)"913" 
 [1] = > string(2)"95"
 [2] = > string(1)"3"
 }
 array(4) {
 [0] = > string(3)"913"
 [1] = > string(2)"95"
 [2] = > string(1)"3"
 [3] = > string(1)"6"
 }
 array(5) {
 [0] = > string(3)"913"
 [1] = > string(2)"95"
 [2] = > string(1)"3"
 [3] = > string(1)"6"
 [4] = > string(1)"0"
 }

can't seem to access it with <?php echo $array[5]; ?> sorry again for the dumb question

• Peon: How about print_r( $array[4] ); ?
• John Conde: Arrays in PHP are zero based. This means you would use $array[4] to get the fifth array.
• rnldpbln: undefined offset. really weird :(
• Peon: Are you sure you are looking at the right array?
• rnldpbln: yep. the array $array contains the json above, i am really stumped by this.

Answer 1

Arrays are zero-indexed. Which means 0 is the first item, 1 the second, etc.

Try <?php print_r($array[4]) ?> :)

$arr = array(
 array("913"),
 array("913", "95"),
 array("913", "95", "3"),
 array("913", "95", "3", "6"),
 array("913", "95", "3", "6", "0")
);
var_dump($arr);
//output
/*
array(5) {
 [0]=>
 array(1) {
 [0]=>
 string(3) "913"
 }
 [1]=>
 array(2) {
 [0]=>
 string(3) "913"
 [1]=>
 string(2) "95"
 }
 [2]=>
 array(3) {
 [0]=>
 string(3) "913"
 [1]=>
 string(2) "95"
 [2]=>
 string(1) "3"
 }
 [3]=>
 array(4) {
 [0]=>
 string(3) "913"
 [1]=>
 string(2) "95"
 [2]=>
 string(1) "3"
 [3]=>
 string(1) "6"
 }
 [4]=>
 array(5) {
 [0]=>
 string(3) "913"
 [1]=>
 string(2) "95"
 [2]=>
 string(1) "3"
 [3]=>
 string(1) "6"
 [4]=>
 string(1) "0"
 }
}
*/
print_r($arr[4]);
//Output : Array ( [0] => 913 [1] => 95 [2] => 3 [3] => 6 [4] => 0 ) 
// loop through 5th array
foreach($arr[4] as $key => $val) {
 echo $key." => ".$val."<br/>";
}
// Output
/* 
0 => 913
1 => 95
2 => 3
3 => 6
4 => 0
*/
echo "Third value : ".$arr[4][2];
//Third value : 3 

Answer 3

By default, array values start with 0, so the 5th element would be #4:

print_r( $array[4] );
