Some functions:

1. array_search () function

?

Array_search (value, array, strict)

?

The array_search () function is the same as the in_array () function. you can find a key value in the array. If this value is found, the key name of the matching element is returned. If not found, false is returned.

?

2 .? Var_export ()? Function

?

?

This function returns the structure information about the variables passed to this function. it is similar to var_dump (). The difference is that the returned representation is legal PHP code.

You can set the second parameter of the function to TRUE to return the expression of the variable.
