修改数组中的变量然后重新插入它[关闭]

Question

Hi all basically I want to take a value from an array, modify it and then insert it as a new variable in the array. I kind of imagine it looking like follows but as I have never really worked with arrays I have no idea.

<?php
    $foobar = array(
        "foo" => "foo1",
        "bar" => "bar1",
    )

 $New_variable = "<img src="$foobar["foo"])">";

 $foobar[foo_img] = $New_variable;
 print_r $foobar;
?>

Hope that makes sense and thankyou in advance.

There are syntax errors in your code.

Try this

$foobar = array(
        "foo" => "foo1",
        "bar" => "bar1"
);

$New_variable = "<img src='".$foobar['foo']."'>";

$foobar['foo_img'] = $New_variable;
print_r($foobar);
