PHP and ce img

Hello

Why can’t I place this in ce-img? <?php echo “$kentekenM”; ?> is there a way around that or plugin that can do that?

‘$kentekenM’ comes from another database

{exp:ce_img:single src="/images/uploads/kentekenplaat.gif" text=" <?php echo "$kentekenM"; ?>|0,0|36|36|#000|system/expressionengine/third_party/ce_img/fonts/kenteken.ttf|left||left,top|52,18|100||||" alt="kenteken {last_segment}” title=”{last_segment}” }

This is working fine

{exp:ce_img:single src="/images/uploads/kentekenplaat.gif" text=" {last_segment}|0,0|36|36|#000|system/expressionengine/third_party/ce_img/fonts/kenteken.ttf|left||left,top|52,18|100||||” alt=”kenteken {last_segment}” title=”{last_segment}” }

Or

{exp:ce_img:single src="/images/uploads/kentekenplaat.gif" text=" {title}|0,0|36|36|#000|system/expressionengine/third_party/ce_img/fonts/kenteken.ttf|left||left,top|52,18|100||||” alt=”kenteken {last_segment}” title=”{last_segment}” }
