CPU Optimization Strategies

Before Optimization

for ($i = 0; $i < 1000000; $i++) {
    $result[] = str_shuffle('abcdefg');
}

Execution Time: 12.3s CPU Usage: 92%

After Optimization

$result = array_map(fn() => substr(str_shuffle('abcdefg'), 0, 7), range(1, 1000000));

Execution Time: 3.8s CPU Usage: 54%

Optimization Recipes

Avoid String Concatenation

// Bad
$result = "";
for ($i = 0; $i < 1000000; $i++) {
    $result .= "a";
}

// Good
$result = str_repeat("a", 1000000);

Use Built-in Functions

// Bad
$sum = 0;
for($i = 0; $i < 1000; $i++) {
    $sum += $i;
}

// Good
$sum = array_sum(range(0, 999));
