Is order of variables important in php?<\/p>\n<\/blockquote>\n

Order of statements is. PHP does things in the order you tell it to do them.<\/p>\n

\n

if php processes variables from top to bottom then ,why does “echo $url” not display the value of first variable<\/p>\n<\/blockquote>\n

It does. It’s just that that variable no longer has the value you gave it on line 1 because you gave it a new value on line 3.<\/p>\n

\n

And in this situation how will I be able to echo the value of first variable?<\/p>\n<\/blockquote>\n

There are lots of approaches to that and \u2026<\/p>\n

\n

Do I need to move the first variable from top to middle?<\/p>\n<\/blockquote>\n

\u2026 would do it, but makes the line $url=\"$url$uri\";<\/code> entirely pointless. <\/p>\n

\n

You need to step back and think about what you actually want to achieve. <\/p>\n

If you need to keep the URL to the site root around and<\/em> have the combined URL available somewhere, then maybe introducing a third variable name is the way forward.<\/p>\n

If you are just debugging and want to make sure the value of $url<\/code> is right before you change it, then you should probably move your echo<\/code> statement instead.<\/p>\n<\/p><\/div>\n
