To insert PHP array values into a Chart.js line chart, you will need to do the following steps:
- Create a canvas element in your HTML file where the line chart will be displayed. Give it an id so that you can refer to it later in your JavaScript code.

|
<canvas id="lineChart"></canvas>
|
- Add the necessary script tag to include the Chart.js library to your HTML file.

|
<script src="https://cdn.jsdelivr.net/npm/chart.js"></script>
|
- Fetch the PHP array values using AJAX or by directly including the PHP code in your HTML file.
- Convert the PHP array values into a JavaScript array using json_encode() function.

<?php
$phpArray = ["value1", "value2", "value3"]; // Replace with your PHP array
$jsArray = json_encode($phpArray);
?>

- Create a JavaScript variable and assign the converted PHP array values to it.

<script>
var ctx = document.getElementById('lineChart').getContext('2d');
var lineChart = new Chart(ctx, {
type: 'line',
data: {
labels: ['Label1', 'Label2', 'Label3'], // Replace with your labels
datasets: [{
label: 'My Line Chart',
data: jsArray,
backgroundColor: 'rgba(255, 99, 132, 0.2)', // Replace with your desired colors
borderColor: 'rgba(255, 99, 132, 1)', // Replace with your desired colors
borderWidth: 1
}]
},
options: {
scales: {
y: {
beginAtZero: true
}
}
}
});
</script>

Note: Make sure to replace the labels
array with the appropriate labels for your data. Also, modify the data
property to use your JavaScript array variable (jsArray
) instead of the sample array shown above.
This will create a line chart using Chart.js with the values from your PHP array.
