How to get single variables out of 3 dimensional array? - php

Question

I've got something I think it is a 3 dimensional array:
$var = '1,Tony,186|2,Andrea,163|3,Peter,178|4,Sally,172';
So there are 2 arrays packed inside the variable. First is separated by | the second one by ,
What I need to do is: separate them and then check for an ID located before the name and give me single variables of the rest.
I tried it like this:
<?php
$personid = 3;
$var = '1,Tony,186|2,Andrea,163|3,Peter,178|4,Sally,172';
$array = explode('|',$var);
foreach($array as $values) {
$arr = explode(",",$values);
foreach($arr as $value) {
if($value[0] == $personid) {
$id = $value[0];
$name = $value[1];
$height = $value[2];
$killloop = 1;
}
}
if($killloop == 1) {
break;
}
}
echo 'ID: '.$id.'<br> Name: '.$name.'<br> Height: '.$height;
?>
But all i get then is:
ID: 3
Name:
Height:
Can anyone help out?

There is no need loop Into Second Array, You already have defined positions.
Always Use break statement to end a Loop immediately, Its a good practice
<?php
$personid = 3;
$var = '1,Tony,186|2,Andrea,163|3,Peter,178|4,Sally,172';
$array = explode('|',$var);
foreach($array as $values) {
$arr = explode(",",$values);
if(!empty($arr) && $arr[0] == $personid){
$id = $arr[0];
$name = $arr[1];
$height = $arr[2];
break;
}
}
echo 'ID: '.$id.'<br> Name: '.$name.'<br> Height: '.$height;
?>
