*/ for (size_t i = 0; i < sizeof(arr) / sizeof(arr[0]); i++) { /* In each iteration, the memory location of 8 is going to be dereferenced and set to arr[i]. As a result, the last value will be equal to the value before it */ *current = arr[i]; printf("Current:%d\n", *current); } return 0; } Just as PHP's $value remains a reference to the last element after a by-reference foreach, current here remains a pointer to arr[3]. Every iteration of the second loop writes into arr[3], ultimately copying the second-to-last value onto the last element. ... Definitely relevant for PHP 7+ 1. You can't change array during iteration Foreach WILL NOT LOOP through new values added to the array <?php while inside the loop.

Use a foreach loop, it loops through all the key=>value pairs:

 foreach($array as value){
     print "$key holds $value\n";
 }

Or to answer your question completely:

 foreach($array as $value){
     print $value."\n";
 }
