I want to have a query that will select all the records that contain a specific one of these items that is in the array. Something like this: select * from table WHERE ( an item in my array ) = '$n' Hopefully that makes sense. Any ideas would be greatly appreciated. Thanks 回答1: So you mean to use MySQL to search in a PHP array that has been serialized with the serialize command and stored in a database field? My first reaction

This is also my first application with jQuery, so forgive me if I'm doing something dumb. I have the following function: function getRandomImages(limit) { imagesArray = new Array(); $.getJSON('createImageArray.php', {limit: limit}, function(data) { $.each(data, function(i) { imagesArray[i] = data[i]; //imagesArray is declared globally. }); }); } The getJSON is correctly grabbing the JSON object. It returns something like this: {"image0":"images/19.10

Here's how you'd do it: $array['Something']['More']['id'] If you particularly wanted access multidimensional arrays with a single string, then you could build a function to do that:

If I save an anonymous function into an array after passing it a variable as parameter, then I change the variable and invoke the function, it prints the last value of the variable, not the value of the variable at the moment I pushed the anonymous function into my array. I simplify my code in the following example: var arr = []; function myFunction(index) { alert(index); } function doPush() { var k = 'hello'; var f = function(){myFunction(k);}; arr.push(f);

I'm learning C and I'm confused at what the difference is between the following two arrays: int a[10]; and int *b = (int *) malloc(10 * sizeof(int)); Just on the most basic level, what is the difference between these two? 回答1: int a[10]; is allocated on stack and is de-allocated as soon as the scope ends. int *b = (int *) malloc(10 * sizeof(int)); is allocated on heap and is alive throughout the lifetime of the program unless it's explicitly free d. 回答2:

My understanding of np.argsort() is that np.sort(array) == array[np.argsort(array)] should be True . I have found out that this is indeed correct if np.ndim(array) == 2 , but it gives different results if np.ndim(array) > 2 . Example: >>> array = np.array([[[ 0.81774634, 0.62078744], [ 0.43912609, 0.29718462]], [[ 0.1266578 , 0.82282054], [ 0.98180375, 0.79134389]]]) >>>

The CGI sets the $QUERY_STRING environment variable by reading everything after the ? in the URL. For example, http://example.com?a=123&b=456&c=ok sets QUERY_STRING=a=123&b=456&c=ok . Somewhere I found the following ugliness: b=$(echo "$QUERY_STRING" | sed -n 's/^.*b=\([^&]*\).*$/\1/p' | sed "s/%20/ /g") which will set $b to whatever was found in $QUERY_STRING for b . However, my script has grown to have over ten input parameters. Is there an easier way to automatically convert the parameters
