\nI’m a big fan of Stack Overflow<\/a> and I tend to contribute regularly (am currently in the top 0.X%<\/a>).\u00a0In this category (stackoverflow<\/a>)\u00a0of posts I will will be posting my top rated questions and answers. This, btw, is allowed as explained in the meta thread here<\/a>.<\/p>\n

My question<\/a> was:<\/p>\n

I am wondering how to rewrite this code to work with qq:<\/p>\n

  $containerRight = <<<qq\r\n    <div class=\"container_right\">\r\n        {echoLikeBox()}\r\n\r\n        <div class=\"join_us\"><a href=\"#\"><img src=\"images\/join_us.png\" width=\"304\" height=\"44\" alt=\"\"><\/a><\/div>\r\n\r\n        <div class=\"box2\"><a href=\"#\"><img src=\"images\/twitter_big.gif\" width=\"304\" height=\"292\" alt=\"\"><\/a><\/div>\r\n\r\n        <div class=\"box3\"><a href=\"#\"><img src=\"images\/facebook.jpg\" width=\"304\" height=\"257\" alt=\"\"><\/a><\/div>\r\n\r\n        <div class=\"box4\"><a href=\"#\"><img src=\"images\/google_ads.gif\" width=\"304\" height=\"164\" alt=\"\"><\/a><\/div>\r\n    <!-- container_right end --><\/div>;\r\n    qq;\r\n    echo $containerRight;<\/pre>\n
The problem is that I don’t know how to echo function inside the <<<. The code for the echoLikBox() is this:<\/p>\n
function echoLikeBox()\r\n{\r\n    $likeBox = <<<qq\r\n    <div class=\"box1\">\r\n            <div class=\"box1_lft\"><a href=\"#\"><img src=\"images\/tweet.jpg\" width=\"108\" height=\"20\" alt=\"\"><\/a><\/div>\r\n            <div class=\"box1_rht\"><a href=\"#\"><img src=\"images\/like.jpg\" width=\"82\" height=\"20\" alt=\"\"><\/a><\/div>\r\n            <div class=\"clear\"><\/div>\r\n    <\/div><!-- box1 end -->\r\n    qq;\r\n    echo $likeBox;\r\n}<\/pre>\n
edit: found the solution here: Calling PHP functions within HEREDOC strings<\/a><\/p><\/blockquote>\n
 <\/p>\n
The answer, by user Gavin Anderegg<\/a>, was:<\/p>\n
You may want to change the “echoLikeBox()” function to, instead of echoing its contents, store them as a string. You can’t make a call to a function inside of heredoc strings, but you can output variables. So, for example, you could have:<\/p>\n
function echoLikeBox()\r\n{\r\n    $likeBox = <<<qq\r\n    <div class=\"box1\">\r\n            <div class=\"box1_lft\"><a href=\"#\"><img src=\"images\/tweet.jpg\" width=\"108\" height=\"20\" alt=\"\"><\/a><\/div>\r\n            <div class=\"box1_rht\"><a href=\"#\"><img src=\"images\/like.jpg\" width=\"82\" height=\"20\" alt=\"\"><\/a><\/div>\r\n            <div class=\"clear\"><\/div>\r\n    <\/div><!-- box1 end -->\r\nqq;\r\n    return $likeBox;\r\n}<\/pre>\n
and then just<\/p>\n
$likeBox = echoLikeBox();\r\n\r\n$containerRight = <<<qq\r\n    <div class=\"container_right\">\r\n        $likeBox\r\n\r\n        ...<\/pre>\n
inside of the main body.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
