The PHP function explode lets you take a string and blow it up into smaller pieces. For example, if you had a sentence you could ask explode to use the sentence’s spaces ” ” as dynamite and it would blow up the sentence into separate words, which would be stored in an array. The sentence “Hello, world, PHP is amazing language.” would look like this after explode got done with it:
1. Hello,
2. world,
3. PHP
4. is
5. amazing
6. language
PHP Explode Example
<?php $Number = "888-111-2222"; $Pieces = explode("-", $Number); // note "-" // We are asking the script to break pieces from left and right side of - // This thing determines that what is separating the parts of a whole thing echo "Whole Number = $Number <br />"; echo "Piece 1 = $num[0]<br />"; echo "Piece 2 = $num[1]<br />"; echo "Piece 3 = $num[2]"; ?>
Result
Whole Number = 888-111-2222 Piece 1 = 888 Piece 2 = 111 Piece 3 = 2222
Random – Another Example
<?php $animals = "cat mouse dog horse snake"; $selected = explode(" ", $animals); // In this case our breaking point is a space and not - // in 23423*343*7897678 the breaking point can be * echo "All = $animals <br />"; echo "Second = $selected[1]<br />"; echo "Fourth = $selected[3]<br />"; echo "First = $selected[0]"; ?>
Result
All = cat mouse dog horse snake Second = mouse Fourth = horse First = cat
