![]() The solution is to use the strict checking option. The following example demonstrates how to create a two-dimensional array, how to specify keys for associative arrays, and how to skip-and-continue numeric indices in normal arrays. It is completely correct behaviour, due to PHP's leniency on variable types, but in "real-life" is almost useless. ![]() Loose checking returns some crazy, counter-intuitive results when used with certain arrays. 1 How is the original output generated, it would be better to fix this than process the data a second time. Similarly, you can declare a three-dimensional (3d) array. You can think the array as a table with 3 rows and each row has 4 columns. For example, Here, x is a two-dimensional (2d) array. Both array got key questionid thats the key I want to target on. Also arrayintersectkey() doesnt what I want, I hope someone can help me out. arraymerge() doesnt work because than I lost some keys + values. One array Ive got the Questions and the Other are the answers. These arrays are known as multidimensional arrays. I have a problem to combine two arrays together. If you can change them to simply use numeric keys, arraymerge () will take care of reindexing them. It looks like you are using something like file-1, file-2, etc. Getting Started Introduction A simple tutorial Language Reference Basic syntax Types Variables Constants Expressions Operators Control Structures Functions Classes and Objects Namespaces Enumerations Errors Exceptions Fibers Generators Attributes References Explained Predefined Variables Predefined Exceptions Predefined Interfaces and Classes Predefined Attributes Context options and parameters Supported Protocols and Wrappers Security Introduction General considerations Installed as CGI binary Installed as an Apache module Session Security Filesystem Security Database Security Error Reporting User Submitted Data Hiding PHP Keeping Current Features HTTP authentication with PHP Cookies Sessions Dealing with XForms Handling file uploads Using remote files Connection handling Persistent Database Connections Command line usage Garbage Collection DTrace Dynamic Tracing Function Reference Affecting PHP's Behaviour Audio Formats Manipulation Authentication Services Command Line Specific Extensions Compression and Archive Extensions Cryptography Extensions Database Extensions Date and Time Related Extensions File System Related Extensions Human Language and Character Encoding Support Image Processing and Generation Mail Related Extensions Mathematical Extensions Non-Text MIME Output Process Control Extensions Other Basic Extensions Other Services Search Engine Extensions Server Specific Extensions Session Extensions Text Processing Variable and Type Related Extensions Web Services Windows Only Extensions XML Manipulation GUI Extensions Keyboard Shortcuts ?
