Php combine arrays

Appending or merging is a common array operation.

It returns the resulting array. If the input arrays have the same string keys, then the values for these keys are merged together into an array, and this is done recursively, so that if one of the values is an array itself, the function will merge it with a corresponding entry in another array too. If, however, the arrays have the same numeric key, the later value will not overwrite the original value, but will be appended. An array of values resulted from merging the arguments together. If called without any arguments, returns an empty array. Version Description 7. Formerly, at least one parameter has been required.

You may give the function a single array or as many as you like. Notice that if the keys of two or more array elements are the same, the last one takes precedence. This function combines the elements or values from two or more arrays into a single array. The values of one array are appended to the end of the previous array during the merging process. The function takes as a parameter a list of arrays that need to be combined, separated by commas, and returns a new array with the merged values of the arrays passed in parameter. If the string keys in both input arrays are the same, the later value for that key would overwrite the previous one. If the arrays contain numeric keys, the later value will be appended to the original value rather than overwriting it. In the result list, values in the input arrays with numeric keys will be renumbered with incrementing keys starting at zero. Any number of arrays can be passed as a parameter. Return Value: It returns a new array containing the elements of all arrays passed in as parameters, with the values of one array appended to the end of the previous array. When two elements have the same string key, the latter value takes precedence. Starting with zero, the integer keys will be renumbered.
