ftp_rename()

Sara only reaches for ftp_rename() when a ftp_rename dry-run has to stay correct in a first job task.

Keep ftp_rename() small. Sara should finish a ftp_rename dry-run in a few lines, not a 40-line dump.

ftp_rename() exists so Sara can keep a ftp_rename dry-run correct in a first job task.

Sara ships ftp_rename() in a first job task. That is the use case worth saying.

ftp_rename() miss — only reciting the name of ftp_rename. Fix it before you talk about advanced PHP.

After ftp_rename(), Sara should still remember only reciting the name of ftp_rename.

One breath for ftp_rename(), then a ftp_rename dry-run, then only reciting the name of ftp_rename. Sit down.

Exam tip

Say ftp_rename() in one breath, then one ftp_rename step Sara can write from memory, then only reciting the name of ftp_rename.

Example

<?php
// ftp_rename()
$scores = [80, 90, 70];
$avg = array_sum($scores) / count($scores);
echo "avg=" . number_format($avg, 1) . "\n";
foreach ($scores as $s) {
  if ($s >= 80) echo "high: $s\n";
}

ftp_rename(): scores array, print avg, then high marks. Say the output.

Short notes

Defftp_rename() — Sara uses it for a ftp_rename dry-run in a first job task.
Ruleftp_rename() → one ftp_rename step Sara can write from memory.
Rememberftp_rename() + Apache/Nginx (a first job task).
Useftp_rename() in a first job task (a ftp_rename dry-run).
Trapftp_rename() — only reciting the name of ftp_rename.
Exftp_rename() → a ftp_rename dry-run.
