PHP - Print array variable gives error

Question

I'm trying this: print "This is my car number $this->attr['number'] ... \n";

But i get this error: Array to string conversion ...

How can i solve this syntax error and use " instead of '?

This is because $this->attr['number']is an array. Just var_dump() it and use the key for which you want the value to be printed. — D4V1D

@D4V1D you are wrong. PHP is evaluating $this->attr as the variable. — Christopher

Err, no! Again, $this->attr['number'] outputs an array, just as PHP just told you. You should access values of this array by doing $this->attr['number']['key']. — D4V1D

@D4V1D sorry but again, you are wrong. Please read the PHP manual (php.net/manual/en/language.types.string.php) and Ctrl+F for "Complex (curly) syntax". — Christopher

print "This is my car number {$this->attr['number']} ... \n";

Putting variable in {} should solve your problem, because php evaluate it as one variable
