How to Extract a Google Data API ID Using Regular Expressions or Built-In String Functions?

Extracting a Google Data API ID using Regular Expressions

To extract the ID from a Google data API URL, we must target the portion after the last forward slash (/). This can be achieved using regular expressions.

In PHP, the following regular expression can be used:

[^/]+$

This expression:

• Ensures at least one character that is not a slash (/).
• Captures until the end of the string, storing the matched portion in the main group.

However, consider using the language's built-in string list processing functions, as they are often more efficient than regular expressions. For PHP, strrchr() can be employed:

<code class="php">strrchr(Text, '/')</code>

This function retrieves the characters after the last occurrence of '/'.

Note: This result includes the slash character itself. To remove it, use substr() as follows:

<code class="php">substr(strrchr(Text, '/'), 1);</code>
