Array values will be present in a format so that keys and elements can show. Definition and Usage The array () function is used to create an array. Print_r: It is used to display the variable information in a human-readable format. We can use var_dump() or print_r() to display the values of an array in human-readable format or to see the output value of the program array. To display array structure and values in PHP, we can use two functions. If given an array, values will be presented in a format that shows keys and elements.

Prior to PHP 8.0.0, a string needle will match an array value of 0 in non-strict mode, and vice versa. These lines of code will return us the first element from the array. If the third parameter strict is set to true then the inarray () function will also check the types of the needle in the haystack. $arr = ĭisplays structured information about expressions that includes its type and value. myarr array(100, 200, 300, 400, 00) echo reset(myarr). Prints human-readable information about a variable. There are multiple functions for printing array content that each has features.
