We have to integrate HTML code inside PHP script to display the pages to browser after proper formatting. For this we have to convert HTML code to PHP script and display or return them to browser. This is very much required when we have to integrate a PHP script in a HTML template. There are two ways to do this. One way is to echo or print the html tags inside the PHP code and the second way is to close the PHP script execution area and return to HTML mode and display the HTML tags.   The second way is not advisable for large pages with more code as that will slow down the page as each time script has to transit from PHP to HTML mode. By printing the same HTML code from inside the PHP code we can get same result and comparable less load or delay in file execution. But in this case we have to take care some points as double quotes inside echo command of a PHP script is not allowed.  The code below will generate error 

<?
echo "<table width="100%" border='0' cellspacing='1' cellpadding='0'>";  // Double quotes inside this line not allowed.
?>

There are two ways to solve this . One is to use single quotes in place of double quotes or to use PHP escape command ( \ ) to tell PHP not to consider the character next to it while evaluating. Here is the correct code using escape command. 

 <?
echo "<table width=\"100%\" border='0' cellspacing='1' cellpadding='0'>";  
?>

This way any number of HTML tags can be converted to PHP code
