The names array is changed to using barcode generating for .net control to generate, create code 39 full ascii image in .net applications. Customer Bar Code array("derick ret barcode 39 for .NET hans", "stig s ther bakken", "andi gutmans");. However, names us ually start with an uppercase letter. You can uppercase the rst letter by using either the /e modi er or preg_replace_callback(). The /e modi er uses the replacement string to be evaluated as PHP code.

Its return value is the replacement string:. < php $names = Code 39 for .NET array( "rethans, derick", "s ther bakken, stig", "gutmans, andi" ); $names = preg_replace("@([^,]+).\ (.

*)@e", "ucwords("\\2 \\1")", $names); >. Gutmans_ch09 Page 297 Thursday, September 23, 2004 2:47 PM 9.3 Regular Expressions If you need to do more complex manipulation with the matched patterns, evaluating replacement strings becomes complicated. You can use the preg_replace_callback() function instead:. < php function USS Code 39 for .NET format_string($matches) { return ucwords("{$matches[2]} {$matches[1]}"); } $names = array( "rethans, derick", "s ther bakken, stig", "gutmans, andi" ); $names = preg_replace_callback( "@([^,]+).\ (.

*)@", // pattern "format_string", // callback function $names // array with "subjects" ); print_r($names); >. Here s one more u seful example:. < php $show_wi Visual Studio .NET barcode 39 th_vat = true; $format = "€ %.2f"; $exchange_rate = 1.

2444; function currency_output_vat ($data) { $price = $data[1]; $vat_percent = $data[2];. $show_vat = isset ($_GLOBALS["show_with_vat"]) && $_GLOBALS["show_with_vat"];. $amount = ($show_ Code 3/9 for .NET vat) $price * (1 + $vat_percent / 100) : $price;. return sprintf( $ GLOBALS["format"], $amount / $GLOBALS["exchange_rate"] );. Gutmans_ch09 Page 298 Thursday, September 23, 2004 2:47 PM Mainstream Extensions Chap. 9 } $data = "This i tem costs {amount: 27.95 %19%} ". "and the other one costs {amount: 29.

95 %0%}.\n"; echo preg_replace_callback ( "/\{amount\:\ ([0-9.]+)\ \%([0-9.

]+)\%\}/", "currency_output_vat", $data ); >. This example orig barcode 39 for .NET inates from a webshop where the format and exchange rate are decoupled from the text, which is stored in a cache le. With this solution, it is possible to use caching techniques and still have a dynamic exchange rate.

preg_replace() and preg_replace_callback() allow the pattern to be an array of patterns. When an array is passed as the rst parameter, every pattern is matched against the subject. preg_replace() also enables you to pass an array for the replacement string when the rst parameter is an array with patterns:.

< php $text = "This is a nice text; with punctuation AND capitals"; $patterns = array("@[A-Z]@e", "@[\W]@", "@_+@"); $replacements = array("strtolower(\\0)", "_", "_"); $text = preg_replace($patterns, $replacements, $text); echo $text."\n"; >. The rst pattern barcode 3/9 for .NET @[A-Z]@e matches any uppercase character and, because the e modi er is used, the accompanying replacement string strtolower(\\0) is evaluated as PHP code. The second pattern [\W\] matches all non-word characters and, because the second replacement string is simply _, all non-word characters are replaced by the underscore (_).

Because the replacements are done in order, the third pattern matches the already modi ed subject, replacing all multiple occurrences of _ with one. The subject string contains the following after each pattern/replacement match, as shown in Table 9.4.

. Table 9.4 Replace ment Steps Step Before: Step 1: Step 2: Step 3: Result This is a nice text; with punctuation AND capitals this is a nice text; with punctuation and capitals this_is_a_nice_text__with_punctuation_and_capitals this_is_a_nice_text_with_punctuation_and_capitals.

3 Splitting barcode 3/9 for .NET Strings T h e l a s t g r o u p o f f u n c t i o n s i n c l u d e s o n l y preg_split(), which can be used to split a string into substrings by using a regular expression match for the delimiters. PHP provides an explode() function that also splits strings, but explode() can only use a simple string as the delimiter.

explode() is much faster than using a regular expression, so you might be better off using explode() when possible. A simple example of preg_splits() s usage might be to split a string into the words it contains. See the following example:.

< php $str = " This is an example for preg_split()."; $words = preg_split("@[\W]+@", $str); print_r($words); >. The script outputs Array ( [0] [1] [ 2] [3] [4] [5] [6] ).
