php array_push() functionsyntax

Function: Add one or more elements (push) to the end of the array of the first parameter, and then return the length of the new array.

Syntax: array_push(array,value1,value2...)

Parameters:

ParametersDescription
arrayRequired. Specifies an array.
value1Required. Specifies the value to add.
value2Optional. Specifies the value to add.

Note: Even if there are string key names in the array, the elements you add are always numeric keys. If you use array_push() to add a unit to an array, it is better to use $array[] =, because there is no additional burden of calling the function. array_push() will issue a warning if the first argument is not an array. This is different from the behavior of $var[], which creates a new array.
