引号不在php中工作

Question

I am using php. This code does not work:

<?php
$str="<?palash";
print($str);

no output but it works as soon as I introduce a space between < and ?

<?php
$str="< ?palash";
print($str);// prints '< ?palash'

Answer 1

It doesn't print <b?palash because it has special characters in it.

If you want to print string with special characters then you should use htmlentities function: print htmlentities($str);
