php what if string to search is '$b' text search?

[sdowney717]

like do this

$pos = strpos($fileline, "$b");

will that work since the editor is showing $b as a variable?
what I want is for strpos to look for $b itself as text.
do you backslash escape it?

not that i know anything about php but if it's anything like bash with strings try single quotes '$b'
http://php.net/manual/en/language.types.string.php
according to that page ' ' is literal string and " " is string with variable expansion.
of course escaping works too.

Hello,

I would use single quotes as it will be treated as a literal string.

You wanna use single quotes. Double quotes will just show the value of $b in quotes.
Example:


$b = 'Hello'
echo $b;

Output:

Hello


echo '$b';

Output:

$b


echo "$b";

Output:

Hello
