Let's say I have a file which goes like this:
<?php
if(isset($_GET['cat_id'])){
$cat_id = $_GET['cat_id'];
$get_cat_pro = "select * from products where cat_id='$cat_id'";
$run_cat_pro = mysqli_query($con,$get_cat_pro);
while($row_cat_pro=mysqli_fetch_array($run_cat_pro)){
$pro_id = $row_cat_pro['product_id'];
$pro_title = $row_cat_pro['product_title'];
$pro_cat = $row_cat_pro['cat_id'];
$pro_brand = $row_cat_pro['brand_id'];
$pro_desc = $row_cat_pro['product_desc'];
$pro_price = $row_cat_pro['product_price'];
$pro_image = $row_cat_pro['product_img1'];
echo "
<section>
<div class='container'>
<div class='row'>
"include_once 'php/includes/overall/widget.php'"
<div class='col-sm-9 padding-right'>
<div class='features_items'><!--features_items-->
<h2 class='title text-center'>Products</h2>
<ul class='pagination'>
<li class='active'>1</li>
<li><a href=''>2</a></li>
<li><a href=''>3</a></li>
<li><a href=''>»</a></li>
</ul>
</div><!--features_items-->
</div>
</div>
</div>
</section>
";
}
}
?>
And in this file I want to echo out an include_once command but I don't know the proper way to do this while echoing some html text.. So I get this error message as well:
Parse error: syntax error, unexpected 'include_once' (T_INCLUDE_ONCE), expecting ',' or ';' on line 19
And the line 19 is this:
"include_once 'php/includes/overall/widget.php'"
So how to correct this issue?

Answer 1

When you want to get into PHP context, you have to put <?php ?> tags in your HTML. Here you are using echo to output HTML from PHP, and requiring to do PHP again. If you want the HTML to switch to PHP to execute the include_once, you have to put the tags again. In your code, the include_once is viewed as HTML, which is not correct, hence the error.
But it gets a bit crazy with php that echos HTML, that requires PHP. So why not simply exit the PHP context to output your html, and get back in for the include_once?
Like so:
<?php
if(isset($_GET['cat_id']))
{
$cat_id = $_GET['cat_id'];
$get_cat_pro = "select * from products where cat_id='$cat_id'";
$run_cat_pro = mysqli_query($con,$get_cat_pro);
while($row_cat_pro=mysqli_fetch_array($run_cat_pro))
{
$pro_id = $row_cat_pro['product_id'];
$pro_title = $row_cat_pro['product_title'];
$pro_cat = $row_cat_pro['cat_id'];
$pro_brand = $row_cat_pro['brand_id'];
$pro_desc = $row_cat_pro['product_desc'];
$pro_price = $row_cat_pro['product_price'];
$pro_image = $row_cat_pro['product_img1'];
?>
<section>
<div class='container'>
<div class='row'>
<?php include_once('php/includes/overall/widget.php'); ?>
<div class='col-sm-9 padding-right'>
<div class='features_items'><!--features_items-->
<h2 class='title text-center'>Products</h2>
<ul class='pagination'>
<li class='active'>1</li>
<li><a href=''>2</a></li>
<li><a href=''>3</a></li>
<li><a href=''>»</a></li>
</ul>
</div><!--features_items-->
</div>
</div>
</div>
</section>
<?php
}
}
?>

Try the following...
Because you started the echo with " you can't have " inside it, you can only use " again when the echo is ending or when you're connecting it to another string.
As you can see I connected it by using periods like so:
...ss='row'>" . include_once ('php/includes/overall/widget.php'); ."<div clas...
<?php
if(isset($_GET['cat_id'])){
$cat_id = $_GET['cat_id'];
$get_cat_pro = "select * from products where cat_id='$cat_id'";
$run_cat_pro = mysqli_query($con,$get_cat_pro);
while($row_cat_pro=mysqli_fetch_array($run_cat_pro)){
$pro_id = $row_cat_pro['product_id'];
$pro_title = $row_cat_pro['product_title'];
$pro_cat = $row_cat_pro['cat_id'];
$pro_brand = $row_cat_pro['brand_id'];
$pro_desc = $row_cat_pro['product_desc'];
$pro_price = $row_cat_pro['product_price'];
$pro_image = $row_cat_pro['product_img1'];
echo "
<section>
<div class='container'>
<div class='row'>".
include_once ('php/includes/overall/widget.php');
."<div class='col-sm-9 padding-right'>
<div class='features_items'><!--features_items-->
<h2 class='title text-center'>Products</h2>
<ul class='pagination'>
<li class='active'>1</li>
<li><a href=''>2</a></li>
<li><a href=''>3</a></li>
<li><a href=''>»</a></li>
</ul>
</div><!--features_items-->
</div>
</div>
</div>
</section>
";
}
}

echo "
<section>
<div class='container'>
<div class='row'>";
include_once 'php/includes/overall/widget.php';
echo " <div class='col-sm-9 padding-right'>
<div class='features_items'><!--features_items-->
<h2 class='title text-center'>Products</h2>
<ul class='pagination'>
<li class='active'>1</li>
<li><a href=''>2</a></li>
<li><a href=''>3</a></li>
<li><a href=''>»</a></li>
</ul>
</div><!--features_items-->
</div>
</div>
</div>
</section>
";

First off, since you want to echo a multiline string, I'd use Heredoc.
You could use fread(). Here's an example of what that would look like.
$str = fread(fopen('php/includes/overall/widget.php', 'a+'), filesize('php/includes/overall/widget.php'));
echo "
ALL YOUR HTML
{$str}
SOME MORE HTML";
