I need to use dynamic variable names to create an article template:
$templatesAr = array("intro","paragraphs","image","conclusion","h2");
$intro = "Intro";
$paragraphs = "Paragraphs";
$image = "image.png";
$conclusion = "Conclusion";
$h2 = "Heading";
$articletemplateAr = array("h2", "intro", "image",
"h2", "paragraphs", "h2", "conclusion");`
How to echo $article in order from $articletemplateAr:
$article = $h2 . $intro . $image . $h2 . $paragraphs . $h2 . $conclusion;
Use this code:
$article = '';
foreach($articletemplateAr as $item) {
$article .= $$item;
}
PHP variable variables are documented here. You can use ${$articletemplateAr[$i]} to access the variable whose name is in the array element.
However, almost any time you find yourself wanting variable variables, a better approach is to use an associative array.
$values = array(
'intro' => "Intro",
'paragraphs' => "Paragraphs",
'image' => "image.png",
'conclusion' => "Conclusion",
'h2' => "Heading"
);
Then you can use $values[$articletemplateAr[$i]].
The reason this is better is because the you can't inadvertently access unintended variables, you're limited to the elements in the array. This is especially important if the elements of $articletemplateAr come from an external source.
