implode — Join array elements with a string
$glue , array $pieces )$pieces )Join array elements with a glue string.

implode() can, for historical reasons, accept its parameters in either order. For consistency with explode() , however, it may be less confusing to use the documented order of arguments.
glue Defaults to an empty string.
pieces The array of strings to implode.
Returns a string containing a string representation of all the array elements in the same order, with the glue string between each element.
| 版本 | 说明 |
|---|---|
| 4.3.0 | The glue parameter became optional. |
Example #1 implode() example
<?php $array = array( ‘lastname‘ , ‘email‘ , ‘phone‘ ); $comma_separated = implode ( "," , $array ); echo $comma_separated ; // lastname,email,phone // Empty string when using an empty array: var_dump ( implode ( ‘hello‘ , array())); // string(0) "" ?>
Note: 此函数可安全用于二进制对象。
