Based on this example http://php.net/manual/en/function.current.php#116128 i would like to add the following. As Vasily points out in his example
<?php
$prices = array(
0 => '1300990',
1 => '500',
2 => '600'
);
foreach($prices as $key => $price){
if($price < 1000){
unset($prices[$key]);
}
}
var_dump(current($prices)); // bool(false)
?>
The above example will not work and return false for version of PHP between 5.2.4 and 5.6.29. The issue is not present on PHP versions >= 7.0.1
A different workaround (at least from Vasily's example) would be to use reset() before using current() in order to reset the array pointer to start.
<?php
$prices = array(
0 => '1300990',
1 => '500',
2 => '600'
);
foreach($prices as $key => $price){
if($price < 1000){
unset($prices[$key]);
}
}
reset($prices);
var_dump(current($prices)); // string(7) "1300990"
?>
