I have the following array:
array(1) {
[0]=> array(3) {
["s2member_level1"] => string(3) "400"
["s2member_level2"] => string(3) "400"
["administrator"] => string(3) "500"
}
}
I want the values s2members_level1, s2members_level2, administratorand their values which are440, 400, 500 using a for loop so that I can update these values to their records.
Your data is 'hidden' in nested array. You can access it with $yourData[0]. To modify values, you can loop over the values and use reference:
foreach ($data[0] as $key => &$value) {
$value = $value * 2;
}
In $key variable you will get s2member_level1, s2member_level2 and administrator.
well, you should use PHP's array function:
$myArray = array("anotherArray" => array("myDesiredValue"));
array_walk_recursive($myArray, function(&$value){
if($value == "myDesiredValue")
{
$value = "ValueChanged";
}
});
// Now the $myArray is:
$myArray = array("anotherArray" => array("ValueChanged"));
The above function loops through every individual member of all the arrays (no matter nested) and applys the changes you like. In our case, I said if the value is "myDesiredValue" then please do something. Note that I use & before $value in function to tell to PHP that directly change the real value of the array, so, after this function, you function is changed.
