Correct memory usage estimation in range() documentation

[rururu3]

Hello,
I found that the PHP manual states that executing range(0, 1000000) uses more than 100MB of memory (link to the documentation). However, when I tested it, the actual memory usage was around 18MB, which is significantly lower than the documented value.
Here is the test script I used:

<?php
    // Memory usage before execution
    $memoryUsageBefore = memory_get_usage(true) / 1024 / 1024;
    echo "Used memory before process: " . $memoryUsageBefore . " MB" . PHP_EOL;

    $arr = range(0, 1000000);

    // Memory usage after execution
    $memoryUsageAfter = memory_get_usage(true) / 1024 / 1024;
    echo "Used memory after process: " . $memoryUsageAfter . " MB" . PHP_EOL;

Given this discrepancy, I suggest updating the documentation to reflect a more accurate memory usage estimate (e.g., 10MB instead of 100MB).
Please let me know if further testing or clarification is needed.
Thank you!
