How to formulate a form with a variable in php

Question

I'm trying to modify an existing html which is output using echo.

<form action="/" id="searchForm" method="post">

I want to replace the "/" with $targetHost.

I can't seem to get the syntax correct.

Any help is much appreciated.

<form action="<?= $targetHost ?>" id="searchForm" method="post">

<?= $targetHost ?> is a shorthand for <?php echo $targetHost ?>

I tried that using this snippet: <?php $targetHost="/mobile/index.php"; $matrix ='<form action="<?= $targetHost ?>" id="searchForm" method="post">'; echo $matrix .'<br/>'; The output looks like this: <form action="<?= $targetHost ?>" id="searchForm" method="post"><br/>

if your html is wrapped in a string then you don't need to worry about the <?= ?>. Just use regular string concatenation.

<?php $targetHost="/mobile/index.php"; $matrix = '<form action=' . $targetHost . ' id="searchForm" method="POST"><p>Hello World</p></form><br/>';  echo $matrix;

?>
