Explosion analysis error ('-', 'foo-bar') [0] (for example)

Question

Why php does not support this syntax:

$s = explode('-', 'foo-bar')[0];

?

Answer 1

This is a limitation in the PHP parser. There is no reason why he cannot support this form of contraction, just not.

Answer 2

You can write it with list:

list($first_value) = explode(‘-’,‘foo-bar’);

Answer 3

‘foo-bar’)[0] php. , ​​, PHP . :

explode(‘-’, ‘foo-bar’);

Answer 4

Instead, you can use this if you are forced to use inline: substr ($ var, 0, strrpos ($ var, '-')); But I prefer a list solution, it's more elegant!
