PHP get index of last inserted item in array
我有阵列或多变的长度,希望能迅速而容易地了解最后一个项目在阵列中的价值(实际上不将其从阵列中删除)。 我怎么能够把最后的项目列入议程,而实际上却不将其从阵列中删除?
Try end
<?php
$fruits = array( apple , banana , cranberry );
echo end($fruits); // cranberry
?>
For numeric (non-associative) zero-based array you can use this:
$arr = array( one , two , three , four , five );
print $arr[count($arr)-1]; // five
Use array end So if I have an array:
$array_example = array( one , two , three );
我要谈最后一个项目,我可以这样做:
echo end($array_example);
这将反映阵列的最后部分,但不会影响阵列。
在这样做之后,如果你想要重新确定阵列中第一个项目的内部阵列点(以便你能够继续正常工作),那么就重新确定阵列点:
reset($array_example);
最后一期=1美元
