Como poderia otimizar este código PHP JS?

Stack Overflow em Português Asked by Wanderson Borges on September 27, 2021

Tenho este código em PHP e JS que busca no BD as visitas que o site X recebeu no mês atual e joga em um gráfico do Google Charts.

Apesar de estar funcional e me servir bem até então, eu fico incomodado com a aparência e o tamanho disto e gostaria muito de saber se teria alguma forma melhor de executar essa mesma tarefa com um código bem mais limpo e inteligente.

Desde já agradeço qualquer contribuição.

Segue abaixo trecho em PHP:

    '06'=>'Junho',
    '07'=>'Julho',

você pode fazer um array de $TotalViewsdia:

<?php
$meses = array(
    '01' => 'Janeiro',
    '02' => 'Fevereiro',
    '03' => 'Março',
    '04' => 'Abril',
    '05' => 'Maio',
    '06' => 'Junho',
    '07' => 'Julho',
    '08' => 'Agosto',
    '09' => 'Setembro',
    '10' => 'Outubro',
    '11' => 'Novembro',
    '12' => 'Dezembro'
);

$mes_atual_nome = $meses[date('m')];

$mes_atual = date('m');
$ano_atual = date('Y');

$TotalViewsdia = [];
for ($i=1; $i < 32; $i++) { 
    $ReadViewsDia = ExeRead("pageviews WHERE pageview_dia = '$i' AND pageview_mes = '$mes_atual' AND pageview_ano = '$ano_atual'");
    $numViewsDia = mysqli_num_rows($ReadViewsDia);

    $TotalViewsdia[$i] = ($numViewsDia > 0) ? $numViewsDia : 0;
}

No script você pode rodar o foreach listando os valores do array:

google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);

function drawChart() {
var data = google.visualization.arrayToDataTable([
['Dias', {type: 'string', role: 'annotation'}, 'Todas as visitas', 'Visitas únicas ao site'],

<?php
foreach ($TotalViewsdia as $key => $value) {
?>
    ['Dia <?=$key?>', '', <?= $value ?>, 0],
<?php
}
?>
    ]);
var options = {
chartArea : { top:20 },
vAxis: {minValue: 0},
curveType: 'function',
backgroundColor: 'none',
legend: { position: 'bottom' },
annotations: { style: 'line' },
colors: ['#15A0C8', '#dc3912'],
pointSize: 7,
series: {
0: { pointShape: 'circle' },
1: { pointShape: 'triangle' },
2: { pointShape: 'square' },
3: { pointShape: 'diamond' },
4: { pointShape: 'star' },
5: { pointShape: 'polygon' }
}
};

var chart = new google.visualization.AreaChart(document.getElementById('curve_chart'));
chart.draw(data, options);
}
