php strlen() – Get the Length of String Variable in php

March 29, 2022 Leave a Comment

In php, the strlen() function allows us to get number of characters and length of a string variable.

When working with string variables in our php programs, it is useful to be able to easily extract information about the values of the strings. In php, we can get the length of a string with the php strlen() function.

strlen() returns the length, or the number of characters, of a string.

To use strlen() , pass a string variable and strlen() will return the string length.

Below is a simple example in php of how to use strlen() to get the length of a string variable.

Examples of Using the php strlen() Function

strlen() is a very useful function and there are a number of examples of how we can use strlen() .

One example is if you want to loop over the characters in a string. You can use range() and loop from 0 to the length of the string.

Another example of using the php strlen() function is if you want to get a substring of the last handful of characters.

Below is an example in php of how to get a substring of the last three characters using substr() and strlen() .

Hopefully this article has been useful for you to learn how to use the php strlen() function to find the length of string variables in your php programs.

How to get Length of String in PHP?

In this tutorial, you shall learn how to get the length of a string in PHP using strlen() function, with examples.

PHP String Length

To get the length of a string in PHP, you can use strlen() function. Pass the string as argument to strlen() and the function returns an integer representing the length of string.

In the following example, we will take a PHP String literal and find its length using strlen() function.

Variable variables

Sometimes it is convenient to be able to have variable variable names. That is, a variable name which can be set and used dynamically. A normal variable is set with a statement such as:

A variable variable takes the value of a variable and treats that as the name of a variable. In the above example, hello , can be used as the name of a variable by using two dollar signs. i.e.

At this point two variables have been defined and stored in the PHP symbol tree: $a with contents "hello" and $hello with contents "world". Therefore, this statement:

produces the exact same output as:

i.e. they both produce: hello world .

In order to use variable variables with arrays, you have to resolve an ambiguity problem. That is, if you write $$a[1] then the parser needs to know if you meant to use $a[1] as a variable, or if you wanted $$a as the variable and then the [1] index from that variable. The syntax for resolving this ambiguity is: ${$a[1]} for the first case and ${$a}[1] for the second.

Class properties may also be accessed using variable property names. The variable property name will be resolved within the scope from which the call is made. For instance, if you have an expression such as $foo->$bar , then the local scope will be examined for $bar and its value will be used as the name of the property of $foo . This is also true if $bar is an array access.

Curly braces may also be used, to clearly delimit the property name. They are most useful when accessing values within a property that contains an array, when the property name is made of multiple parts, or when the property name contains characters that are not otherwise valid (e.g. from json_decode() or SimpleXML ).

Example #1 Variable property example

The above example will output:

Please note that variable variables cannot be used with PHP's Superglobal arrays within functions or class methods. The variable $this is also a special variable that cannot be referenced dynamically.

PHP Array Length Tutorial – How to Get an Array Size

Arrays are a powerful data type in PHP. And knowing how to quickly determine the size of an array is a useful skill.

In this article I'll give you a quick overview of how arrays work, and then I'll dive into how to get the size of PHP arrays.

If you already know what arrays are, you can jump straight ahead to the How to get an Array size? section.

What is an Array in PHP?

Before we dive into getting an array size, we need to make sure we understand what an array is. An array in PHP is a variable type that allows you to store more than one piece of data.

For example, if you were storing a simple string, you would use a PHP string type:

However, if you wanted to store a few more pieces of separate data, you might consider using a couple of string variables.

That's all well and good, but what if you need to store more data, and quickly recall any of those items elsewhere in your code? That's where an array comes in handy. You can still store the individual pieces of data but using a single variable.

Each item in that array can be referenced by its numeric key. So instead of needing to recall the single variables, you could reference a single array item by its numeric key.

For even more control, arrays also allow you to define your own array keys, using a string.

This allows you to also reference the array item by its string key.

You can also define arrays using the new short array notation, which is similar to JavaScript:

Arrays can also be nested, forming more complex array variables:

And, you can recall a specific array value using its nested key:

However, if you find yourself regularly doing this, you might want to consider using objects rather than arrays.

Arrays are useful if you need to quickly gather and then use different pieces of related data in a function, or pass that data to another function.

By putting these pieces of data into an array, you have fewer variables defined, and it can make your code easier to read and understand later on. It's also a lot easier to pass a single array variable to another function than it is to pass multiple strings.

How to Get the Size of an Array in PHP

Usually when we talk about the size of an array, we're talking about how many elements exist in that array. There are two common ways to get the size of an array.

The most popular way is to use the PHP count() function. As the function name says, count() will return a count of the elements of an array. But how we use the count() function depends on the array structure.

Let's look at the two example arrays we defined earlier.

In this example, count($post_data) will result in 3. This is because there are 3 elements in that array: 'heading', 'subheading', and 'author'. But what about our second, nested array example?

Believe it or not, in this example, count($post_data) will also return 3. This is because by default the count() function only counts the top level array elements.

If you take a look at the function definition , you will see that it accepts two arguments – the array to be counted, and a mode integer. The default value for that mode is the predefined constant COUNT_NORMAL , which tells the function to only count the top level array elements.

If we pass the predefined constant COUNT_RECURSIVE instead, it will run through all levels of nesting, and count those instead.

Now, the result of count($post_data, COUNT_RECURSIVE) will be, as expected, 5.

"But wait!", I hear you cry. "you mentioned there was another way?".

Well yes, the other function you can use is sizeof() . However, sizeof() is just an alias of count() , and many folks assume (rightly so) that sizeof() would return the memory usage of an array.

Therefore it's better to stick with count() , which is a much more suitable name for what you are doing – counting elements in an array.

Thanks for reading! I hope you now have a better understanding of how to find the size of an array in PHP.

How to limit string length in PHP ?

A string is a sequence of characters in PHP. The length of the string can be limited in PHP using various in-built functions, wherein the string character count can be restricted. 

Approach 1 (Using for loop): The str_split() function can be used to convert the specified string into the array object. The array elements are individual characters stored at individual indices. 

Parameters:  

  • $string – The string to split into array

Example: A for loop iteration is performed over the array object until the desired length. The characters are displayed until the length is equivalent to the desired number of characters. 

Approach 2 (Using mb_strimwidth() function): The mb_strimwidth function is used to get truncated string with specified width. It takes as input the string and the required number of characters.
