I wanted to compare the type of 2 vars.
1st method: Use this Funktion (gettype) and compare with ==
2nd method: Compare every type per is_[type]
Here a little Benchmark:
(I had to break line twice..)
<?php
$var1 = "Hallo";
$var2 = "Käsekuchen";
$var3 = 3.141526;
$Start = microtime(true);
for($i=0;$i<10000;$i++)
{
if(is_bool($var1)&&is_bool($var2)||is_int($var1)&&
is_int($var2)||is_string($var1)&&is_string($var2)||
is_object($var1)&&is_object($var2)||is_array($var1)
&&is_array($var2))
{
//same
}
if(is_bool($var3)&&is_bool($var2)||is_int($var3)&&
is_int($var2)||is_string($var3)&&is_string($var2)||
is_object($var3)&&is_object($var2)||is_array($var3)
&&is_array($var2))
{
//same
}
}
$time = microtime(true)-$Start;
echo "Zeit fuer if abfrage: ".$time."<br>";
$Start = microtime(true);
for($i=0;$i<10000;$i++)
{
if(gettype($var1)==gettype($var2))
{
//same
}
if(gettype($var3)==gettype($var2))
{
//same
}
}
$time = microtime(true)-$Start;
echo "Zeit fuer funktion : ".$time;
?>
Output:
Zeit fuer if abfrage: 0.0257611274719
Zeit fuer funktion : 0.0139331817627
So the function isnt so slow...
