You can also use theforstatement to loop through an associative array in PHP. The following code will produce the same result: $age=array('John'=>40,'Mia'=>29,'Joe'=>20);$keys=array_keys($age);for($i=0;$i<count($keys);$i++){echo"{$keys[$i]}is{$age[$keys[$i]]}years ...
In this version, we do not explicitly create an array at all. The array is created for us when we add the first element to it.$prices['Tires'] = 100; $prices['Oil'] = 10; $prices['Spark Plugs'] = 4;Using Loops with Associative Arrays...
(Speaking of which: Gabriel's version doesn't work as written; it reports associative arrays as numeric if only the first key is non-numeric, or if the keys are numeric but ordered backwards. Michael solves this problem by comparing array_reduce() to count(), but that costs another ...
$myarray = array("id"=>$theid, "name"=>name($id), "text"=>$row2[text]); There are multiple points. Probably most important is, as that is inside a loop, you overwrite $myarray in each iteration. You want to add to an array instead. Let's do this: $myarray = array();...
3.is_array():判断变量是否是数组类型 image.png 4.键值相关函数 1)array_keys() 返回数组中元素的键名组成的数组。 image.png 2)array_values() 返回数组中所有元素的值组成的数组。 image.png 3)array_combine(键数组,值数组) 创建一个数组,用键数组的值作为键名。
