Bug description: strstr matches any variable surrounded by underscores
This script:
<?php
$needle = "foo";
echo "1: ";
echo strstr("Moo _bar_", "_$needle_");
echo "<br>2: ";
echo strstr("Moo _bar_", "_{$needle}_");
echo "<br>3: ";
echo strstr("Moo _foo_", "_{$needle}_");
echo "<br>4: ";
echo strstr("Moo !bar!", "!$needle!");
?>
Gives this output:
1: _bar_
2:
3: _foo_
4:
Obviously, the line 1 is the problem. If both "haystack" and "needle" have
the strings surrounded by underscores - the strings are matched even if
they are actually different. This happens only if the "needle" has a
variable between the underscores, and the variable is not surrounded by {
and }.
Prehaps I am missing something and the combination of "_$" is supposed to
mean something, but i did not see it in the documentation.
