PHP implode () function
PHP String function
Instance
To combine array elements into strings:
<?php$arr = Array (' Hello ', ' world! ', ' I ', ' love ', ' shanghai! '); echo Implode ("", $arr);
?>
Running an instance
The first parameter is optional, so it can also be called.
echo Implode ("", $arr);
echo implode ($arr);
Definition and usage
The implode () function returns a string that is composed of array elements.
Note: the implode () function accepts two parameter orders. However, for historical reasons, explode () is not possible, and you must ensure that the separator parameter precedes the string parameter.
Note: The separator parameter of the implode () function is optional. However, for backwards compatibility, it is recommended that you use two parameters.
Note: This function is binary safe.
