PHP Learning notes PHP Array Summary

foreach ($arr as $key = $value) { echo $value. " "; } Copy Code 2), when the assignment is made with $arr[], the bidding clubs under the array is subscript with the current maximum subscript +1 ($arr [Maximum +1]). Example: $value) {echo $key. ' = '. $value. " "; } Output:/*0 =11 =str2 =4 =45 =xint2 =76 =xx*/?> 4, in PHP, the array is self-increment, and in C + + is different 5, about the function of the array 1), count the number of statistics array. 2), IsArray to determine if a variable is not an array of 3), explode text segmentation. 4), unset destroy the elements of a variable or array.

Let's summarize these, hope to help you. To learn PHP programming, you come to the programmer's home.
