在变量的开头添加一些东西？

Question

I am looking for some code that allows you to add +44 onto the beginning of my $string variable.

So the ending product would be:

$string = 071111111111

[phone]

Answer 1

Your $string variable isn't actually a string in this scenario; it's an integer. Make it a string by putting quotes around it:

$string = "071111111111"

Then you can use the . operator to append one string to another, so you could do this:

$string = "+44" . $string

Now $string is [phone]. You can read more about how to use the . (string concatenation operator) on the PHP documentation here.

Other people's suggestions of just keeping $string as an integer wouldn't work: "+44" . 071111111111 is actually [phone]. Due to the 0 at the start of the number, PHP converts it to an octal number rather than a decimal one.
