PHP shorthand for isset()? -

this question has answer here:

• what php shorthand for: print var if var exist 10 answers

is there shorthand way assign variable if doesn't exist in php?

if(!isset($var) {   $var = ""; } 

i'd like

$var = $var | ""; 

update php 7 (thanks shock_gone_wild)

php 7 introduces called null coalescing operator simplifies below statements to:

$var = $var ?? "default"; 

before php 7

no, there no special operator or special syntax this. however, use ternary operator:

$var = isset($var) ? $var : "default"; 

or this:

isset($var) ?: $var = 'default';
