PHP string concatenation


String concatenation is the string manipulation method when you join 2 or more strings together.

In PHP it is a quite easy task. You can use the concatenation operator which is the u2018.u2019 (dot). You can join 2 or more strings into one as follows:

$str1 = 'This';

$str2 = 'is a';

$str3 = 'string';

$full = $str1.' '.$str2.' '.$str3;

echo $full; // This is a string

Besides this you can use the operator to append a string to an existing one like this:

$str = 'Main string';

$str .= ' plus another string';

echo $str; // Main string plus another string

If you concatenate a string with a number, the number will (automatically) be converted into a string value, so the output will be u201Cstringu201D:

$num = 100;

$str = $num.' is a number';

echo $str; // 100 is a number
