Adding strings together....

Hi, With Richard Edens... I've read the tutorial about PHP but i can't find annything for the following simple problem... Adding strings together... In javascript for instance this might look like this: ---- var text_alpha = "hallo "; var text_berta = "world..."; text_alpha = text_alpha + textberta; ---- Witch means that 'text_aplha' became 'hello world...' This even worked with an array: ---- var text_alpha = "hallo "; var text_berta = new Array(); text_berta[0] = "world..." text_alpha = text_alpha + textberta[0]; ---- Now with 'emplode' you can split a string into an Array like with javascript. but how can i add every array element with an enter key like '\n' to a string??? Witch in javascript this would look like: ---- text_alpha = text_alpha + textberta[0] + '\n'; ---- Thanks... ...Richard
