You can use this script to test the speed of both methods. On my machine, this method takes about 1/4 the time of using is_array().Ĭast the value to an array, then check (using =) if it is identical to the original. If you use is_array() millions of times, you will notice a *huge* difference. I've found a faster way of determining an array. In PHP, objects can be converted into JSON String using the PHP function json_encode().Ī common use of JSON is to read data from a web server and display the data on a web page.Įxample the above example, we assign the value to the object variable, and then, in json_encode(), we convert the matter to the array variable and make the associative array.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 ?

Then, explode() function breaks this string into an array. In the above example, a string variable is assigned some value. The first is for the separator, the second for array_name, and the last for the limit. explode() functionīy using explode() function, we can convert a string into an array of elements. For that, we can use PHP's explode() function. You can also convert that string into an array if required. The first is the separator, and the other one is the array_name. Two parameters are passed in the implode() function. The implode() function will convert the array into a string in the following line. In the above example, an array variable is declared and assigned some values at the first line. The separator parameter in implode() function is optional. There are two ways to convert an array into a string in PHP.īy using the implode() function, we can convert all array elements into a string. This code explains how to convert an array to a string in PHP using implode function. We often need to convert a PHP array to a string.
