So it's the same as the previous example except that the word fart with a \b word boundary does not exist in the content: farty. Php> echo preg_match('(\bdart\b|\bfart\b)', $gun4) ![]() Php> echo preg_match('(\bdart\b|\bfart\b)', $gun3) Php> echo preg_match('(\bdart\b|\bfart\b)', $gun2) Php> echo preg_match('(\bdart\b|\bfart\b)', $gun1) Match literal words on the commandline with word boundaries. To fix this, enforce word boundaries in regex. However it may be a problem that looking for word fart matches farty. Variables gun1 and gun2 contain the string dart or fart. For advanced users, we've also added ability to find patterns using a. This tool is greedy and it will search for all occurrences of the given text fragment and replace them all. Php> echo preg_match('(dart|fart)', $gun4) First, enter the text pattern you want to replace in search text options, then specify the new content that you want to see in its place in replace text options. Php> echo preg_match('(dart|fart)', $gun3) textarea-options-wrapper div.word-wrap-wrapper input(typecheckbox)word-wrap-checkbox label(forword-wrap. Php> echo preg_match('(dart|fart)', $gun2) Php> echo preg_match('(dart|fart)', $gun1) Match a number of literal words on the commandline with (dart|fart) phpsh $content1 and $content2 contain at least one word, $content3 does not. The preg_match method used the PCRE engine within the PHP language to analyze variables: $content1, $content2 and $content3 with the (\w) pattern. Php> echo preg_match('(\w )', $content3) Php> echo preg_match('(\w )', $content2) Php> echo preg_match('(\w )', $content1) Start phpsh, put some content into a variable, match on word. I'll be using the phpsh interactive shell on Ubuntu 12.10 to demonstrate the PCRE regex engine through the method known as preg_match To match any whole word you would use the pattern (\w )Īssuming you are using PCRE or something similar:Ībove screenshot taken from this live example: Matching any whole word on the commandline with (\w )
