<div class="content wysiwyg-content">
I think I should be able to search for an input field html and replace using the code below, where the variable $html contains a text input field with it's value set to [quantity]. However this depends on the value setting preceding the field's closing tag. Can this pattern match be improved to search for html that starts with '&lt;input', ends with '/&gt;' and contains 'value=&quot;[quantity]&quot;'?<br />

<pre><code id="code-8205858">$new_html = preg_replace('/&lt;input(.*)value=&quot;\[quantity\]&quot; \/&gt;/', $quantity, $html);</code></pre>

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.

A regular expression ("regex") is a sequence of characters that define a search pattern, mainly for use in pattern matching with strings, or string matching, i.e. "find and replace"-like operations. Regular expression processors are found in several search engines, search and replace dialogs of several word processors and text editors, and in the command lines of text processing utilities, such as sed and AWK. Many programming languages provide regular expression capabilities, some built-in, for example Perl, JavaScript, Ruby, AWK, and Tcl, and others via a standard library, for example .NET languages, Java, Python and C++ (since C++11). Most other languages offer regular expressions via a library.
