Though this question seems similar to ones already asked, but this is a different case.
I have a php hook <?php echo zublum_display_breadLocation($pid);?> in my wordpress singular.php that displays 3 different locations, like country, state, city
I also have another code I copied online which outputs the first value before comma (,)
<?php
$var = "1,23,45,123,145,200";
echo $first_word = substr($var, 0, strpos($var, ','));
?>
The problem is when I replace the php hook in my theme with the code I got online, it does not output anything.
This is what I did
<?php
$var = "<?php echo zublum_display_breadLocation($pid);?>";
echo $first_word = substr($var, o, strpos($var, ','));
?>
Please help, it will be much appreciated.
An explode would seem the simplest way
echo explode(',', $var)[0];
