This would create an array holding only the element at the third position. Then, you need to filter the keys to find the ones you want. If you want to extract elements from an array by offset, you have to use $third = array_splice($array, 2, 1) First you need to get an array containing the keys. Which means the element at offset 0 is foo although it's key is 100. The syntax for accessing elements in an associative array is arr'key'.The syntax for accessing properties of objects.
In this instance the key with the lowest value is desired, asort will sort from lowest to highest values and reset the internal pointer. cell is an associative array, not an object. So this structure can not be used instead of original, but can be used with it.
The Offset of an element is completely unrelated to it's key or value print_r( Another approach for retrieving a single string is by using a desirable sorting method and retrieving the first key directly by using key() on the sorted array. My point was - if reconstruct source array in this way, obviously, this may be a reason of loosing multiple values. There are three different kind of arrays and each array value is accessed using an ID c which is called array. For example if you want to store 100 numbers then instead of defining 100 variables its easy to define an array of 100 length. But if you wanted to access the second associative value in that array ( 'some'), you cannot do $array] because that would evaluate to $array and that's baz. An array is a data structure that stores one or more similar type of values in a single value. So when you do $array] you are really doing $array. Likewise, for a mixed array like shown above, the solution with array_keys suggested elsewhere on this site will not work, because print_r( array_keys(array('foo', 'foo' => 'bar', 'baz', 'some' => 'value')) ) It is wrong to assume that just because foo is the first associative key it has anything to do with the actual numeric key 1. As you can see, in that array above, index 1 is associated with baz.
That's the offset, but it has nothing to do with the index 1. From what I've read, including this comment1, using isset is faster than inarray. The foo is the second element in the array. There have been a few discussions about speed when using inarray. When you say you want to set the value of an associative array using the array index of the key/value, then you have to use the given key, setting $array is not the same as setting $array.Ĭonsider this array print_r( array('foo', 'foo' => 'bar', 'baz', 'some' => 'value') ) So trying to differentiate between integers and numeric strings is unnecessary.There is no correlation between numeric and associative index keys. You can use the PHP arrayvalues() function to get all the values of an associative array. In other words, there is no such thing as an array key of "8" because it will always be (silently) converted to the integer 8. Answer: Use the PHP arrayvalues() function. The key() function simply returns the key of the array element that's currently being pointed to by the internal pointer. The indexed and associative array types are the same type in PHP, which can both contain integer and string indices. The key function helped me and is very simple. "8" will be interpreted as 8, while "08" will be interpreted as "08").
PHP ASSOCIATIVE ARRAY GET ALL VALUES HOW TO
see redreggae's answer for how to get just the values. If a key is the standard representation of an integer, it will be interpreted as such (i.e. It won't work anywhere because you're passing a string, not an actual array. From the array documentation:Ī key may be either an integer or a string. Get the value of an associative array if the key or part of the key is matched. Many commenters in this question don't understand how arrays work in PHP. PHP associative array get values in an array.
