PHP explode()

Introduction to PHP explode()

The explode() function of the PHP Programming Language is an inbuilt function which helps in splitting a string into many different strings. The explode() function helps splitting the string based on the string’s delimeter which means that it is going to split the string wherever delimeter character will present/occur. This explode() function will return an array which contains the string/string formed after splitting the string which is original. This PHP explode() function usually accepts only three parameters to split a string into many string elements and stores into an array. It is like cutting the big string into many small strings and so on.

explode(separator1, OriginalString1, No.ofElements1)

How explode() Function works in PHP?

The explode() function of the PHP Programming Language works based on the three parameters mentioned. They are Separator1, OriginalString1 and No.ofElements1 Parameter. It works by splitting the string into smaller strings with the help of the parameters inside the explode() function. All these smaller string elements are stored in array with index values and also based on the parameters of the explode() function.

Explanation of Parameters:

The Parameters of the explode() function are actually accepting three parameters but in those only two parameters are mandatory and one parameter is an optional parameter.

1. Separator1/Delimeter: The Separator1 Parameter of the PHP Programming Language actually specifies some critical points at which point the string has to split which means that whenever the string character will be found in the string element then it is going to symbolize the end of one array element and start of the another. This delimeter/Separator1 parameter is a mandatory parameter.

2. OriginalString1: The OriginalString1 Parameter of the PHP Programming Language is actually an original string which is used to split a string into many strings and stores in an array only if the string characters are available inside of the string. This OriginalString1 parameter is also a mandatory parameter.

3. No.ofElements1/Limit: This Parameter is an optional parameter and it’s not mandatory. This parameter helps in specifying the number of array elements. This parameter can be of any type of integer.

It can be positive integer, negative integer or the zero integer.

  • Positive Integer (N): If No.ofElements1 parameter is passed with Positive Integer value then it means array will contain this number of string elements. If number of elements after separating the elements w.r.t the separator will emerge as to be the value greater then N-1 elements but remains same and the last string element will be the whole remaining string.
  • Negative Integer (N): If the negative integer is passed to the No.ofElements1 parameter then last string element N will be trimmed and the remaining array element will be returned as only one single string.
  • Zero Integer: If the No.ofElements1 parameter is passed with “Zero” value then the array which is going to return only one string element i.e., Full String (whole string). When no value is passed to this No.ofElements1 parameter then array returned will be going to have total number of elements formed after the string separation with the separator.

Return value Type:

The return value type of the explode() function is the single array with the list of the strings.

Examples of PHP explode()

Given below are the examples mentioned:

Example #1

This is the example of splitting a single string into many small string by taking the space in between the string into the consideration. In the below example inside of the PHP tags, a variable “$s1” is created and assigned a string sentence to the $s1 variable. Then print_r() function is used along with the explode() function in it. Here separator1/delimeter parameter is space “ ”, $s1 is the input parameter/Original String and then here no parameter is mentioned. There is no limit/No.ofElements1 parameter here so there is no limit to splitting of the string. After splitting, inside of the array index values small strings will be stored and printed with the help of the print_r() function.

Syntax:

<?php
$s1 = "My Name is Pavan Kumar Sake";
print_r (explode(" ",$s1));
?>

Output:

php explode() 1

Example #2

This is the example of implementing with limit value “0”. At first, a variable “$stra” is created and this variable is also assigned with a string value ‘car1, bus1, motorbike1, cycle1’. Then print_r() function is made along with the explode() function in it. In the explode() function, “,” is used as separator1 parameter, $stra variable value is used as OriginalString1 Parameter and value “0” is used as No.ofElements1 Parameter. It is mentioned in the parameters description that if the No.ofElements1/Limit value is mentioned as 0 then the whole original string is considered as one single string array element. This will be printed as shown in the output. Then print function is used to print line break.

Syntax:

<?php
$stra = 'car1, bus1, motorbike1, cycle1';
print_r(explode(',',$stra,0));
?>

Output:

php explode() 2

Example #3

This is the example of implementing the string splitting with the help of the positive integer as No.ofElements1/limit Parameter. Here at first, a string variable called “$strab” is created with the string value ‘car1, bus1, motorbike1, cycle1’. Then print_r() function is used along with the explode() function along with the three parameters. Here “,” is the Separator1 parameter, “$strab” is the original string element which is nothing but OriginalString1 parameter, “2” is the No.ofElements1/limit Parameter. According to the parameters description, if the positive integer value is passed then n-1 array indexes values will splitted and stored and for N-1 index value, remaining whole string will be printed.

Syntax:

<?php
$strab = 'car1, bus1, motorbike1, cycle1';
print_r(explode(',',$strab,2));
?>

Output:

by using different type of integer values

Example #4

This is the program of implementing the string splitting function by using different type of integer values for No.ofElements1/limit parameter. So that one can know what actually happens for different parameters which are acting inside of the explode() function. For the first explode() function, the whole original string is considered as only one array element. Then value “4” is used for the second explode() function. For this, n-1=3 array indexes string values will be printed but for n-1 array index the whole remaining string will be printed. Then for the third explode() function, negative integer value(-N) is used. So at N array index values the string will be trimmed and will be printed starting from the 0 index value.

Syntax:

<?php
$Original_str1 = "Hello, IamPavan Kumar Sake-Write, BusinessMan, PhysicsNerd.";
print_r (explode (" ",$Original_str1, 0));
print "\n";
print_r (explode (" ",$Original_str1, 4));
print "\n";
print_r (explode (" ",$Original_str1, -3));
print "\n";
?>

Output:

by using different type of integer values
