I am developing a web using PHP. When some of the given condition is not true, I use die() function to terminate the rest of the PHP code execution. But with the termination of the PHP code, the HTML code is also terminated. I want such a function that only terminate the PHP execution and does not effect the HTML.

Solution 1

You could use exit. Have a look at this link:

Good luck!

brother exit also terminates the html code.

Example 3 looked like it did what you looked for but just only for destructors. In the comments below it however there are some ideas about it though. Maybe a flush()/ob_flush() might work before calling exit or die but terminating the request half way would break the html. Some tags might not get closed, like body and html. Would be best to create a proper flow that fully completes. Depending on what kind of project you are working on you will probably come across this later on and it will give you major problems.

Use try catch then throw the exception as html

XML

<html>
    <head><title></title></head>
    <body>
<?php
        echo "Let me see If I can connect to the database.....";
        try
        {
            $myObj= new MyDbWrapper();
            $myObj->connectAndSelectDb('not existing db');
            echo "Yes I am the winner";
        }catch (Exception $e)
        {
            echo $e;
        }
?>
        <!-- your htmls here-->
        <br/>
        <input type="text" name="text1" /><br/>
        <input type="text" name="text2" /><br/>
        <input type="text" name="text2" /><br/>
        <div>Scrape whatever you want</div>
<?php
        class MyDbWrapper
        {
            function connectAndSelectDb($dbName)
            {
                mysql_connect('localhost','root','');
                if(!mysql_select_db($dbName))
                {
                    throw new Exception(mysql_error(). "... Oops an error");
                }
            }
        }

?>
</body>
</html>
