Weird custom function output in wordpress

1 Views

I have a problem with WordPress. I am running this function: 

function name($text = '', $relative = false, $icon = true) {

echo $text;
echo $relative;
echo $icon;

}

and the output of it is just “1” (one). How is it possible? Shouldn’t be 3 lines of code (3 answers)? I am using apache 2.4, php 5.4.1 and wordpress 3.4 beta 3 on windows 7.

  1. if you add wrapper dummies and line breaks to each echo, you’ll find why it is showing just “1”:

    function name($text = '', $relative = false, $icon = true) {

echo "text:".$text.";<br>";
echo "relative:".$relative.";<br>";
echo "icon:".$icon.";<br>";

}

name();

    outputs : 

    text:;
relative:;
icon:1;

  2. Thats correct.

    <?php
$text='';
$relative=false;
$icon=true;

echo $text;
echo $relative;
echo $icon;

?>

    First one is null, second one is false which is treated as 0 which is outputed as null. The last one is true, which is 1. Wich makes the output 1.

    As shown here:

    1

    (output of above script)
