![]() ![]() Find the first match, including its offset. expression with "i", meaning that the match is "caseless". If the "case insensitive" flag is set, then modify the regular This function will take two strings as parameter 'strg1' and 'strg2'. The function has all the logic written within it. Create the regular expression pattern to search for all needles. The first way of comparing strings in PHP is by using the strcmp () function of PHP for easily comparing two strings. * If FALSE then the smallest position from start ofįunction mpstrpos ( $haystack, $needles, $offset = 0, $last = false ) * boolean $last If TRUE then the farthest position from the start If a match is found, the function returns the character position of the first match. * characters counted from the beginning of the The PHP strpos() function searches for a specific text within a string. In the case of not detecting the substring, false is returned. Watch a video course Learn object oriented PHP This function is capable of returning the position of the first occurrence of a substring inside a string. * integer $offset If specified, search will start this number of You can apply the strpos () function for checking if a string contains a certain word. * mixed $needles Array containing needles or string containing * string $haystack The string to search in. * the substrings is partially located at the end of the string. * search for multiple needles at once and it wil return a position when one of * This function is simulair to function strpos() except that it allows to * Find the position of the first (partially) occurrence of one or more If( substr ( $needle, 0, $i ) = substr ( $haystack, - $i )) 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 ?
