|
|
Its often beneficial to replace regular expressions with simpler functions
|
|
that have the same effect.

|
|
<example fontsize="1.2em" title="With Regular Expression"><![CDATA[<?php
|
|
if (preg_match ('/(.*)\@(.*)/', $data, $matches)) {
|
|
print $matches[2];
|
|
}
|
|
?>]]></example>
|
|
|
|
<example fontsize="1.2em" title="Without Regular Expressions"><![CDATA[<?php
|
|
$pos = strrpos ('@', $data);
|
|
if ($pos !== false) {
|
|
print substr ($data, $pos);
|
|
}
|
|
?>]]></example>

|
|
In other cases it may help to use regular expressions instead of custom parse
|
|
routines in your PHP code.
