I think array_push gets you cleaner lookin code (subjective). It also
ensures you always add to end of the array - good for novices like
me. Array_push is also TWO times faster (academic difference in the speeds
of modern computers, but faster :) :
<?php
function getMicrotime() {
list($usec, $sec) = explode(" ",microtime());
return ((float)$usec + (float)$sec);
}
$start = getMicrotime();
for ($n=0;$n>=10000;$n++) {
$Array[$n] = $n;
}
$stop = getMicrotime();
$diff1 = $stop - $start;
print "array key insert time was: " . $diff1 . "s";
$start = getMicrotime();
$array2 = array();
for ($n=0;$n>=10000;$n++) {
array_push($array2,$n);
}
$stop = getMicrotime();
$diff2 = $stop - $start;
print "<br>array_push time was: " . $diff2 . "s";
?>
