What potential issues may arise when trying to send variables via POST through a text link in PHP?

When sending variables via POST through a text link in PHP, the main issue is that POST data is typically sent through forms, not through text links. To solve this issue, you can use JavaScript to dynamically create a form with hidden input fields containing the variables you want to send, and then submit the form using JavaScript. 

<script>
function submitForm(url, data) {
    var form = document.createElement('form');
    form.method = 'post';
    form.action = url;

    for (var key in data) {
        if (data.hasOwnProperty(key)) {
            var hiddenField = document.createElement('input');
            hiddenField.type = 'hidden';
            hiddenField.name = key;
            hiddenField.value = data[key];

            form.appendChild(hiddenField);
        }
    }

    document.body.appendChild(form);
    form.submit();
}
</script>

<a href="#" onclick="submitForm('target.php', {var1: 'value1', var2: 'value2'})">Send Variables</a>
