PHP - Reverse of calling a function?

Having some trouble with this..

<?php

EG204_ExoSkel();

function EG204_ExoSkel() { 

    $to_be_end = 'Red';

    everything_loop();

}

function everything_loop() {

    echo $to_be_end;

}

?>

The开发者_运维百科 code above will not echo Red, so I must be trying to use functions backwards. Might that be possible?

All that is in the Everything function is to be apart of different foreach loops.

Try this one (send it as an argument)

<?php
EG204_ExoSkel();

function EG204_ExoSkel() {

    $to_be_end = 'Red';

    everything_loop($to_be_end);

}

function everything_loop($argument) {

    echo $argument;

}
?>

You have scoping issues. The declaration of $to_be_end is only available in the EG204_ExoSkel function.

If you want to use it outside that function you should use global to make it globally available. And also add global in the other function (also to made use of the global variable). Resulting in this:

EG204_ExoSkel();

function EG204_ExoSkel() { 
  global $to_be_end;    
  $to_be_end = 'Red';
  everything_loop();

}

function everything_loop() {
  global $to_be_end;
  echo $to_be_end;
}

Note: using global is considered bad practice and tends to make a mess of your code (and even introduce hard to find bugs). A better solution (if possible in your real code) is to pass on the variable to the other function(s).

Try referencing $to_be_end as a global!

WARNING Global are bad practice Avoid

<?php

EG204_ExoSkel();

function EG204_ExoSkel() { 

global $to_be_end;

$to_be_end = 'Red';

everything_loop();

}

function everything_loop() {

global $to_be_end;

echo $to_be_end;

}

?>
