How to print an array in PHP?
To print an array in PHP, you can use the built-in print_r() function, which prints or displays information about a variable, including its type and value.
Where:
- variable: specifies the array about which we want to get information
- return (Optional): when set to "True", this function will return information, but not print it. The default value is "False".
How to display information about an array in PHP?
To display information about an array in PHP, you can use the var_dump() function, which dumps structured information such as the type and value of a given variable. Arrays and objects are explored recursively with indented values to show structure.
Where:
- variable: defines an array to display information
How to print the elements of an array using a foreach loop in PHP?
To print the elements of an array in PHP, you can use the foreach loop, which provides the easiest way to iterate over the elements of an array. Unlike print_r() or var_dump() , the foreach() loop iterates over the elements of an array in less time.
