<?php _e( 'text', 'textdomain'); ?> is used to translate text in themes and plugins. But what if i have a php function that defines text as a variable:
$textoutput = 'blablabla';
In another document the variable is echoed:
echo $textoutput;
How to translate the 'blablabla' text? $textoutput = _e( 'blablabla', 'textdomain'); doesnt work.
Thank you.
_e( 'blablabla', 'textdomain'); is used for echoing to the browser, not for assignment to a variable.
If you wish to assign it to a variable you need to use a different function which is $variable = __( 'blablabla', 'textdomain')
that means these code lines of code do the same thing
_e( 'blablabla', 'textdomain');
echo __( 'blablabla', 'textdomain');
$variable = __( 'blablabla', 'textdomain');
echo $variable;
