What could the intention be of someone using "\0" in comparison be?

As in, while my first guess would be that they'd meant to use just the
number 0, what would your guesstimate be relating to why someone would in
fact use the following syntax as part of determining if a certain
phrase/string was included in a variable's value?

//start excerpt...
if (strpos ($text, "<b>") >= "\0")
//end excerpt

???

TIA
