I would say that PHP is more Perl-like than C++-like. I started PHP with a
background in Perl and found it very easy to pick up.

Here's an example to demonstrate their similarities.

Perl:

#!/usr/bin/perl

$a = 1;
$b = 1;
$c = undef;
$psi_old = undef;

print "Approximating psi...\n";
while (1)
{
$psi = sprintf('%.08f', $b/$a);
last if ($psi_old eq $psi);
$psi_old = $psi;
print "$psi\n";

$c = $a + $b;
$a = $b;
$b = $c;
}

PHP:

<?php

$a = 1;
$b = 1;
$c = NULL;
$psi_old = NULL;

print "Approximating psi...\n";
while (1)
{
$psi = sprintf('%.08f', $b/$a);
if ($psi_old == $psi) break;
$psi_old = $psi;
print "$psi\n";

$c = $a + $b;
$a = $b;
$b = $c;
}

?>
