9/18/2023 0 Comments Php substring index![]() ![]() Each string has extraneous delimiters around it (inc the ones we added above), so they need to be stripped off Break up the string according to the delimiter character ![]() Add the whole string, untouched to the result array. While (list($arg, $val) = each($getstrings)) $instring toggles so we know if we are in a quoted string or not $getstrings = split('\"', $splitter.$s.$splitter) Adding the delimiter to the ends simplifies the logic further down First step is to split it up into the bits that are surrounded by quotes and the bits that aren't. It seemed to split on a comma even though it was between a pair of quotes. $qstr = substr_replace ( $qstr, '', strrpos ( $qstr, '"' ), 1 ) $qstr = substr_replace ( $qstr, '', strpos ( $qstr, '"' ), 1 ) Remove first and last quotes, then merge pairs of quotes To fix this, I changed the second substr_count to look for an odd number of quotes, as opposed to any quotes at all: In response to the getCSVValues() function posted by justin at cam dot org, my testing indicates that it has a problem with a CSV string like this: I hope this tutorial is helpful.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 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 ?

JavaScript code recipe: split string into array If you’re developing a web application project, it’s better to let the programming language that handles the backend of your application to split the string instead of using MySQL queries.įor example, JavaScript has the split() method that allows you to split a string into an array: | hello | | good morning | | happy to see you | + -+Īnd that’s how you can split a string using a MySQL stored procedure. Here are some results of running the stored procedure:ĬALL splitString ( '1 > 2 > 3', '>' ) - Output:ĬALL splitString ( 'hello # good morning # happy to see you', '#' ) - Output: ![]() Once all string parts are added to the table, the SELECT query will retrieve the rows for the string. The loop will add the parts of the string into the temp_string table, then call the REGEXP_REPLACE() function to remove the part that’s already added to the table. Then, a WHILE loop will be executed as long as the delimiterChar is found in the inputString. The delimiterChar for the string delimiterįirst, the procedure will create a temporary table to store each part of the string until the delimiter position.The inputString for the string to split.The splitString() procedure above accepts two arguments: DELIMITER // CREATE PROCEDURE splitString ( IN inputString text, IN delimiterChar CHAR ( 1 ) ) BEGIN DROP TEMPORARY TABLE IF EXISTS temp_string CREATE TEMPORARY TABLE temp_string ( vals text ) WHILE LOCATE ( delimiterChar, inputString ) > 1 DO INSERT INTO temp_string SELECT SUBSTRING_INDEX ( inputString, delimiterChar, 1 ) SET inputString = REGEXP_REPLACE ( inputString, ( SELECT LEFT ( inputString, LOCATE ( delimiterChar, inputString )) ), '', 1, 1 ) END WHILE INSERT INTO temp_string ( vals ) VALUES ( inputString ) SELECT TRIM ( vals ) FROM temp_string END // DELIMITER ![]()
