How to Split a String Using Multiple Delimiters in PHP?

Separation of Strings Using Multiple Delimiters in PHP

In PHP, splitting strings by multiple delimiters is a common task that requires a tailored approach. Let's consider an example:

<code class="php">$string = "something here ; and there, oh,that's all!";
// Split the string by ";" and "," delimiters</code>

How can we achieve this? The solution lies in utilizing PHP's preg_split() function, which allows for splitting based on regular expressions.

<code class="php">$pattern = '/[;,]/';

echo '<pre class="brush:php;toolbar:false">', print_r(preg_split($pattern, $string), 1), '

';

In this example, the regular expression /[;,]/ matches any occurrence of either a semicolon (;) or a comma (,):

• / denotes the beginning and end of the regular expression.
• [;,] matches a literal semicolon or comma.
• The [] square brackets create a character class that captures either character.
• The . metacharacter matches any character that isn't a newline.
• The * quantifier indicates that the pattern can match zero or more occurrences.

As a result, the function splits the input string into multiple lines:

something here

and there

oh

that's all!

This technique provides a versatile solution for splitting strings by multiple delimiters in PHP.
