PHP extract () function

If I use PHP's extract () function to import a variable from an array, will a variable with the same name be overwritten? The reason I am asking is because I am trying to initialize all of my variables.

Thank you for your time.

It will be overwritten by default.

http://php.net/extract



If extract_type

[second argument] is not specified, it is assumed thatEXTR_OVERWRITE

See linked page for other options

The default is overwrite, but you can change this to one of several possible options by specifying a collision handling function:

for example pass EXTR_SKIP

, since the second parameter, for example extract($array,EXTR_SKIP)

, will skip collisions.



Full usage is detailed here: http://php.net/manual/en/function.extract.php

It depends entirely on the extract_type value you are using. However, the default needs to be overwritten.

It depends on the second argument you are passing to the function. extract () takes an optional second argument consisting of constants. See Docs at http://us2.php.net/manual/en/function.extract.php
