Merge array items into string [duplicate]

Try this from the PHP manual (implode):

<?php $array = array('lastname', 'email', 'phone'); $comma_separated = implode(",", $array); echo $comma_separated; // lastname, email, and phone // Empty string when using an empty array: var_dump(implode('hello', array())); // string(0) "" ?> 

If you are trying to just concatenate all of strings in the array, then you should look at implode().

$array1 = array( "one", "two", ) $array2 = array( "three", "four", ) $finalarr = array_merge($array1, $array2); $finalarr = implode(",", $finalarr); 

will produce this one,two,three,four

You can use join. It's an alias for implode, and in my opinion more readable:

$fruits = array('apples', 'pears', 'bananas'); echo join(',', $fruits); 

join(" -- ", Array("a", "b")) == "a -- b" 

actually join is an alias for the implode function.

If you want to merge the string representation of a group of objects into a single string, you can use implode on an array of those objects. The objects' classes just have to have the __toString() magic method defined.

class myClass { protected $name; protected $value; public function __construct($name,$value) { $this->name = $name; $this->value = $value; } public function __toString() { return $this->name . '/' . $this->value; } } $obj1 = new myClass('one',1); $obj2 = new myClass('two',2); $obj_array = array($obj1, $obj2); $string_of_all_objects = implode('|',$obj_array); echo $string_of_all_objects; // 'one/1|two/2' 

I found that trick useful to quickly get a string representation of a group of objects for display on a webpage. No need to loop through the object array with foreach and using echo $obj->get('name').

EDIT: And here's and example with a "collection" class. I have 2 outputs (echos) at the end. The 2nd one should work, but I'm not sure about the 1st.

class myCollectionClass implements IteratorAggregate { protected $objects = array(); public function __construct() {}; public function add(myClass $object) { $this->objects[] = $object; return $this; // fluid } public function getIterator() { // for the interface return new ArrayIterator($this->objects); } public function __toString() { return implode($this->objects); } } $my_collection = new myCollectionClass(); $my_collection->add($obj1)->add($obj2); // add both myClass objects to the collection. can do in one line because fluid //echo implode('|',$my_collection); // Comment out myCollectionClass's __toString method to test this. does it work? I'm not sure. But the next line will work thanks to myCollectionClass' __toString, which itself uses myClass's __toString echo $my_collection; // same output as previous block before EDIT. 

$array= array( "Alfred Hitchcock", "Stanley Kubrick", "Martin Scorsese", "Fritz Lang" ); $string=""; foreach ( $tempas $array) { $string=$string.",".$temp; } 

foreach($array as $key => $value) { $string .= $value .' '; } 

For Multi Array such as:

 $multi_arrays = array( 0 => array('model' => 'Product 1'), 1 => array('model' => 'Product 2'), 2 => array('model' => 'Product 3'), 3 => array('model' => 'Product 4')); $pattern = array('/\[/', '/\]/', '/{"model":/', '/}/', '/\"/'); $str_models = preg_replace($pattern, '', json_encode( $multi_arrays)); 

The result will be:

Product 1, Product 2, Product 3, Product 4

You can change pattern for get any result you want!
