Double quotes within php script echo

Question

I have a line of php code that looks like this   echo   lt script gt     edit errors   html   lt h3 gt  lt em gt Please Correct Errors Before Proceeding lt  em gt  lt  h3 gt    lt  script gt      I would like to know how to add a font color to the text correctly  If I do this   echo   lt script gt     edit errors   html   lt h3 gt  lt em gt  lt font color  red  gt Please Correct Errors Before Proceeding lt  font gt  lt  em gt  lt  h3 gt    lt  script gt      The word  red  is in black text and the compiler throws an error   If I use single quotes around red  then the text does not show up at all   Any help would be great  Thanks

You can just forgo the quotes for alphanumeric attributes:

echo "<font color=red> XHTML is not a thing anymore. </font>";
echo "<div class=editorial-note> There, I said it. </div>";

Is perfectly valid in HTML, and though still shunned, absolutely en vogue since HTML5.

CAVEATS

It's only valid for mostly alphanumeric and dash combinations.
Never ever do this with user input appended to attributes (those need quoting and htmlspecialchars or some whitelisting).
See also: When the attribute value can remain unquoted in HTML5
In other news: <font> specifically is somewhat outdated however.

You need to escape    so it won t be interpreted as end of string  Use   to escape it   echo   lt script gt     edit errors   html   lt h3 gt  lt em gt  lt font color   red   gt Please Correct Errors Before Proceeding lt  font gt  lt  em gt  lt  h3 gt    lt  script gt      Read more  strings and escape sequences

if you need to access your variables for an echo statement within your quotes put your variable inside curly brackets  echo  i need to open my lock with its    array  key

use a HEREDOC  which eliminates any need to swap quote types and or escape them   echo  lt  lt  lt EOL  lt script gt     edit errors   html   lt h3 gt  lt em gt  lt font color  red  gt Please Correct Errors Before Proceeding lt  font gt  lt  em gt  lt  h3 gt    lt  script gt  EOL

You need to escape the quotes in the string by adding a backslash   before      Like     lt font color   red   gt
