php – try catch is faster than @ ?

Question:

try {
include('');
} catch(e) {
 die('error');
}

or

@include('') or die('error');

or

if (file_exists('')) {
 include('');
}

or

$result = ('SELECT 1 FROM files WHERE file_name="" LIMIT 1');
if ($result) {
 include('');
}

Answer:

Correct. The dog does not eliminate the error, it only suppresses its conclusion.

And try-catch allows you not only to suppress, but also to take some specific measures. speed is very funny. If everything goes smoothly, this is the fastest way, short of just bare code. When an error occurs – one of the slowest.

<?php
$time = microtime(true);
for($i=0;$i<1000000;$i++){
    @divByZero($i,0);
}
print((microtime(true)-$time).'<br />');
//1.66923713684 - делим на 0
//1.25963785172 - делим на 3

$time = microtime(true);
for($i=0;$i<1000000;$i++){
    try{
        divByZeroE($i,0);
    }catch(Exception $e){

    }
}
print((microtime(true)-$time).'<br />');
//5.61499404907 - делим на 0
//0.690489969254 - делим на 3

$time = microtime(true);
for($i=0;$i<1000000;$i++){
    divByZeroIfOnly($i,0);
}
print((microtime(true)-$time).'<br />');
//0.69531083107 - делим на 0
//0.69578036312 - делим на 3

function divByZero($a,$b){
    return $a/$b;
}

function divByZeroE($a,$b){
    if($b==0)
        throw new Exception('Division By Zero');
    return $a/$b;
}

function divByZeroIfOnly($a,$b){
    if($b==0)
        return false;
    return $a/$b;
}

full now? =)
