The JavaScript String search() function is used to search for a specified string or regular expression within a given string. It returns the index of the first occurrence of the specified search value, or -1 if the search value is not found. The search() function can take a regular expression as its argument, allowing for more complex search patterns. It is a useful tool for finding specific substrings within a larger string and can be used in a variety of applications, such as form validation or data processing.

Javascript String search in PHP With Example Code
JavaScript is a popular programming language used for creating interactive web pages. However, sometimes you may need to use JavaScript functions in PHP. One such function is the search() function, which is used to search for a specified value in a string and returns the position of the match.
To use the search() function in PHP, you can use the preg_match() function. This function searches a string for a pattern and returns true if the pattern is found, and false otherwise.
Here is an example of how to use the preg_match() function to search for a string in PHP:
$string = "Hello, world!";
$search = "/world/";
if (preg_match($search, $string)) {
echo "Match found!";
} else {
echo "Match not found.";
}
In this example, the $string variable contains the string “Hello, world!”, and the $search variable contains the regular expression pattern “/world/”. The preg_match() function is used to search for the pattern in the string, and if a match is found, the message “Match found!” is displayed. If no match is found, the message “Match not found.” is displayed.
Using the preg_match() function in PHP allows you to use the search() function from JavaScript in your PHP code. This can be useful when you need to perform string searches in PHP and want to use a function that you are already familiar with from JavaScript.
Equivalent of Javascript String search in PHP
In conclusion, the equivalent PHP function for the Javascript String search function is the preg_match() function. This function allows you to search for a specific pattern within a string and returns a boolean value indicating whether or not the pattern was found. It also provides additional options for specifying the search pattern and the search location within the string. By using the preg_match() function in PHP, you can easily search for specific strings or patterns within your code and perform various actions based on the results. Whether you are a beginner or an experienced developer, understanding the equivalent PHP function for the Javascript String search function is an important step in mastering PHP programming.
