Here is an example of how to programmatically add a breakpoint based on a condition:

<?php
$blah = 'meh';
if ($blah !== 'blah') {
    phpdbg_break_file('blah.php', 6);
}
$blah = 'blah';
echo $blah;
?>

OUTPUT when running the debugger (using ev to evaluate the value of $blah after each step):

C:\path\to\dir>phpdbg -e blah.php
[Welcome to phpdbg, the interactive PHP debugger, v8.1.6]
